Question 1

Oogenesis always involves an equal division of cell contents in the formation of an egg and polar bodies.

Accepted Answer

During oogenesis, the division of cell contents is unequal, resulting in one large egg and smaller polar bodies that typically do not develop into eggs.

Question 2

Identify which event will occur during prophase I of meiosis but does not occur during prophase of mitosis.

Accepted Answer

During prophase I of meiosis, homologous chromosomes pair up to form bivalents, a process called synapsis, which does not occur during prophase of mitosis.

Question 3

Identify the chromosomal abnormalities as well as the physical features present in a person suffering from Turner syndrome.

Accepted Answer

The answer of Identify the chromosomal abnormalities as well as...

Question 4

Which of the following statements is true about the life cycle of animals?

Accepted Answer

Gametes are the haploid phase in the life cycle of animals, meaning they contain a single set of chromosomes.

Question 5

Study the figure to answer the following questions.  A.Is this cell going through mitosis or meiosis?
B.Explain your answer.
C.Identify the stage.

Accepted Answer

The answer of Study the figure to answer the following...

Question 6

Aneuploidy is a change in the number of chromosomes resulting from nondisjunction during meiosis.

Accepted Answer

Aneuploidy occurs when there is an abnormal number of chromosomes due to nondisjunction, which is the failure of chromosomes to separate properly during meiosis.

Question 7

If the diploid number of chromosomes for an organism is 52,what will the haploid number of chromosomes be?

Accepted Answer

The haploid number is half of the diploid number, so if the diploid number is 52, the haploid number is 26.

Question 8

Sexual reproduction brings about genetic variation within a species.How does sexual reproduction contribute to variation? Why is genetic variation so important to the survival of a species? Support your answer with an example.

Accepted Answer

The answer of Sexual reproduction brings about genetic variation within...

Question 9

The following picture depicts which of the following changes in chromosome structure?

Accepted Answer

The answer of The following picture depicts which of the...

Question 10

A lattice holds the members of a bivalent together in such a way that the RNA of the nonsister chromatids is aligned.

Accepted Answer

A lattice holds the members of a bivalent together in such a way that the DNA of the nonsister chromatids is aligned, not RNA.

Question 11

Jacobs syndrome,XYY,results from nondisjunction during spermatogenesis.

Accepted Answer

Jacobs syndrome, or XYY syndrome, occurs when an extra Y chromosome is present due to nondisjunction during spermatogenesis, leading to a 47,XYY karyotype.

Question 12

Some plants are tetraploid (4n).How might such a plant arise?

Accepted Answer

The answer of Some plants are tetraploid (4n).How might such...

Question 13

The following picture depicts which of the following changes in chromosome structure?

Accepted Answer

The answer of The following picture depicts which of the...

Question 14

Only one of the four daughter cells becomes a functional gamete in spermatogenesis.

Accepted Answer

In spermatogenesis, all four daughter cells (spermatids) become functional sperm cells.

Question 15

Characterize the following statements about changes in chromosome number and structure as True or False.
-Sex chromosome aneuploids are better tolerated and have a better chance of producing survivors.

Accepted Answer

Sex chromosome aneuploids are generally better tolerated than autosomal aneuploids because the body has mechanisms, like X-inactivation, to manage extra sex chromosomes, leading to a higher chance of survival.

Question 16

During ________,the homologous chromosome pairs independently align themselves at the equator of the cell.

Accepted Answer

Independent assortment refers to the process during meiosis I where homologous chromosomes align independently at the equator, leading to genetic variation.

Question 17

It is estimated that an average of two or three crossovers occur per human chromosome.

Accepted Answer

Crossovers, or recombination events, typically occur during meiosis, and it is estimated that each human chromosome undergoes about two to three such events on average, facilitating genetic diversity.

Question 18

During which phase of mitosis and meiosis will the state of the chromosome be the same?

Accepted Answer

The answer of During which phase of mitosis and meiosis...

Question 19

Study the figure depicting the process of spermatogenesis.Name the labeled cells and tell whether they are haploid or diploid.In what part of meiosis is the number of chromosomes reduced by half?

Accepted Answer

The answer of Study the figure depicting the process of...

Question 20

Which of the following statements correctly compares the events of meiosis and mitosis?

Accepted Answer

The answer of Which of the following statements correctly compares...
