❗️❗️❗️❗️❗️
A man with a genetic disease marries a woman who does not carry the disease. It is not
possible for their sons to have the disease, but their daughters will inherit it. The disease
must be

A X-linked dominant.
B Y-linked dominant.
C X-linked recessive,
D Y-linked recessive.

The correct answer is letter A

Men differ from women in that they have one X and another Y chromosome (unlike X, Y has few genes and determines few characteristics), since women have only X chromosomes. X and Y chromosomes have few homologous regions , which makes certain characteristics completely influenced by sex.

An inheritance linked to sex or an inheritance linked to the X chromosome is called one in which the genes are located in a non-homologous region of the X chromosome. In this type of inheritance, females have three genotypes, and the male has only two.
