An Individual with Two Kinds of Gametes (I

Question

An individual with two kinds of gametes (i.e.X bearing and Y bearing)is referred to as:
A) Homogametic
B) Heterogametic
C) Heterozygous
D) None of these
E) All of these

Accepted Answer

An individual with two kinds of gametes (i.e. X bearing and Y bearing) is referred to as heterogametic. Homogametic refers to individuals with only one type of gamete (i.e. XX or YY). Heterozygous refers to individuals with two different alleles of a gene on the homologous chromosomes. None of these options fully describe an individual with two types of gametes. Therefore, the best answer is B, heterogametic.
