Which of the following statements is true concerning a homozygote?
A) Both alleles for a trait are the same in this individual.
B) There is only one copy of a gene for a particular trait.
C) Males are more likely to be homozygous than females.
D) Two different alleles for a trait are present in a homozygote.
E) Homozygotes and heterozygotes will always show the same phenotype.

Question

Quizplus · Accepted Answer

A homozygote is an individual that has the same two alleles for a particular gene. This means that both copies of the gene are the same, which is represented by the term "homozygous." Therefore, statement A is true. Statement B is incorrect because homozygotes have two copies of the same gene. Statement C is also incorrect because there is no gender bias in heterozygosity/homozogosity. Statement D is incorrect because a homozygote has two of the same alleles, not two different alleles. Statement E is not always true because the phenotype of an individual depends on the specific traits and alleles involved.
