Sex-Linked Inheritance
Multiple Choice
Multiple ChoiceX-linked genes differ from Y-linked genes in which of the following ways?
A
Only X-linked genes are technically sex-linked because Y-linked genes affect characteristics unrelated to sex.
B
Sons and daughters can inherit alleles of X-linked genes from fathers proportionally, but only sons inherit alleles of Y-linked genes from their fathers.
C
Genes on the X chromosome are expressed only in females, and genes on the Y chromosome are expressed only in males.
D
Though most X-linked genes determine sex, Y-linked genes control for characters unrelated to sex.
E
Sons and daughters have equal probabilities in inheriting a recessive allele of an X-linked gene from their mother, but only sons can inherit rare Y-linked genetic disorders from their father.
