Question 1

Regarding sexually antagonistic selection as a cause of homosexuality, which of the following statements is FALSE?

Accepted Answer

There is currently no evidence supporting the theory that sexually antagonistic genes are mutations that occur outside the nucleus of the ovum within the mitochondrial tissue. This statement is false.

Question 2

A difference in the size of specific areas of the brain connected to sexual activity have been found in homosexuals and heterosexuals.These specific areas are within which part of the brain?

Accepted Answer

The hypothalamus is the part of the brain that controls sexual behavior, and studies have found differences in size or activity in specific areas of the hypothalamus between homosexuals and heterosexuals.

Question 3

Differences in neurotransmitter levels have been detected in which part of the brain in homosexual and heterosexual persons?

Accepted Answer

Studies have shown differences in the size and activity of the hypothalamus between homosexual and heterosexual individuals. The hypothalamus plays a key role in regulating hormones and sexual behavior, and differences in neurotransmitter levels may contribute to these differences.

Question 4

Rob was raised by gay parents.According to the statistics on sexual orientation, Rob will most likely be

Accepted Answer

While having gay parents may influence a child's attitudes and beliefs regarding sexual orientation, it does not determine their sexual orientation. Studies have shown that having gay parents has no significant effect on a child's sexual orientation. Therefore, it is just as likely for Rob to be heterosexual as it is for him to be homosexual or bisexual.

Question 5

Some male fetuses are exposed to too little testosterone, while some female fetuses are exposed to too much testosterone with these differences impacting sexual orientation, according to which theory of homosexuality?

Accepted Answer

The theory being described is the prenatal hormonal theory, which suggests that differences in exposure to hormones in the womb (specifically, levels of testosterone) may impact sexual orientation.

Question 6

A difference between heterosexuals and homosexuals has been found in their

Accepted Answer

Research has found structural differences in the brains of heterosexuals and homosexuals, particularly in the size and function of certain regions related to sexuality and attraction.

Question 7

Regarding the research on homosexuality, which of the following statements is/are TRUE?​

Accepted Answer

Research suggests that exposure to certain hormones in utero plays a role in sexual orientation. Specifically, the theory referred to in statement B is known as the "prenatal hormone theory" and proposes that sexual orientation is influenced by the level of exposure to testosterone in utero. Statement A is partially true, as some research has found that female relatives of homosexual men have fewer offspring, but this is not a consistent finding. Statement C is not entirely accurate as there is no evidence to suggest that hormone imbalances in adulthood cause homosexuality, and the hormone levels of gay men and lesbians are not necessarily atypical.

Question 8

In research on the causes of homosexuality, scientists have begun to focus on the study of how genes are expressed during development, which is called

Accepted Answer

Scientists have started focusing on the study of epigenetics to understand the role of genes in the development of homosexuality. Epigenetics refers to the changes in gene expression that occur without altering the DNA sequence. These changes can be influenced by environmental factors, such as hormone levels during fetal development, and can have lasting effects on an individual's sexual orientation.

Question 9

In their investigations regarding the causes of homosexuality, researchers have begun to focus on epigenetics, which is the study ofhow

Accepted Answer

Epigenetics is the study of how genes are expressed during development, which can potentially provide insight into the development of various traits and behaviors, including sexual orientation.

Question 10

Regarding the causes of sexual orientation, which of the following statements is FALSE?

Accepted Answer

The statement that homosexuality can be caused by hormone imbalances in adulthood with the hormone levels of most gay men and lesbians being atypical is false. While hormone levels can play a role in sexual orientation, it is believed to occur during prenatal development, not in adulthood.

Question 11

One recent theory of male homosexuality involves genes that are expressed differently in males and females, so that the males with the gene, which increases male attraction, become homosexual, while the females with the gene become heterosexual.This type of gene transmission is called

Accepted Answer

Sexually antagonistic selection occurs when a gene has opposite effects on fitness in males and females. In this theory, the gene that contributes to male homosexuality would increase fitness in females by increasing attraction to males, but decrease fitness in males by causing homosexuality. This type of selection could lead to the maintenance of the gene in the population despite its negative effect on male fitness. Polynomial causation, horizontal gene transfer, and extranuclear inheritance are not relevant to this theory.

Question 12

Dr.Armond is investigating what role genetics play in homosexuality.His research centers on how genes are expressed during development.Dr.Armond's field is called

Accepted Answer

Dr. Armond's research on how genes are expressed during development indicates that he is studying epigenetics, specifically how environmental factors can influence gene expression and potentially contribute to homosexuality. Eugenics is a discredited field that promotes selective breeding to improve the human gene pool, and polygenics refers to the inheritance of traits that are influenced by multiple genes. Bidirectionality is a concept in psychology that suggests that causality can operate in two directions between two variables.

Question 13

Research studies on the cause of homosexuality have shown that

Accepted Answer

Research indicates that hormonal differences during pregnancy can influence areas of the brain related to sexual behavior, suggesting a biological component to sexual orientation. Other options like B, C, and D are not supported by scientific consensus.

Question 14

Regarding sexual orientation, which of the following statements is FALSE?

Accepted Answer

While there are some studies that suggest differences in brain structures and chemicals between heterosexual and homosexual individuals, these differences are not significant enough to be used as definitive factors in determining sexual orientation.

Question 15

According to research findings presented in the textbook, homosexuality appears to be caused by

Accepted Answer

Research findings suggest that genes and/or prenatal hormone levels may play a role in the development of homosexuality. There is no evidence to suggest that poor parenting or sexual abuse causes homosexuality, and while societal acceptance may influence an individual's decision to come out as homosexual, it is not the cause of homosexuality itself.

Question 16

Regarding sexual orientation, which of the following statements is FALSE?

Accepted Answer

The statement that homosexuality is caused by hormone imbalances in adulthood with the hormone levels of most gay men and lesbians being significantly below average is false. There is no evidence to support this claim. Instead, research suggests that sexual orientation is likely influenced by a complex interplay of genetic, hormonal, and environmental factors, but the exact mechanisms are not fully understood.

Question 17

Regarding sexual orientation, which of the following statements is FALSE?

Accepted Answer

The statement that most gay men have lower than normal adult testosterone levels and that adult lesbians have lower than normal estrogen levels is false. Research has not consistently supported these hormonal differences as a factor in determining sexual orientation. Hormone levels in adult gay men and lesbians are typically within the normal range for their gender.

Question 18

One theory of male homosexuality is sexually antagonistic selection, which involves​

Accepted Answer

Sexually antagonistic selection theory suggests that genes that increase the reproductive success of males may have negative effects on females, and vice versa. This could lead to the same genes being expressed differently in males and females, potentially leading to male homosexuality as a result of genetic expression. The other options (A, C, and D) are not relevant to this theory.

Question 19

When the same genes​ involved in sexual attraction are expressed differently in males and females, the gene transmission is referred to as

Accepted Answer

Sexually antagonistic selection refers to the genetic transmission of traits that have opposite effects on the fitness of males and females. In this case, genes involved in sexual attraction are expressing differently in males and females, which can affect their mating success and ultimately, their reproductive fitness.

Question 20

Regarding the research on homosexuality, which of the following statements is/are TRUE?​

Accepted Answer

A) Studies have found that female relatives of homosexual men tend to have more offspring than female relatives of heterosexual men, supporting the "kin selection hypothesis" that suggests genes associated with homosexuality may increase reproductive success in female family members.
B) There is evidence to suggest that variations in prenatal hormone levels can influence sexual orientation development, potentially through altering brain development.
C) While some studies have found differences in hormone levels between homosexuals and heterosexuals, the hormone levels of most gay men and lesbians fall within the normal range.
