Question

PLEASE ANSWER I NEED HELP In a family, the father is affected by a genetic disorder. The son in the family has the same disease, but the daughters do not have it. What type of inheritance is this? A. Y-linked B. X-linked C. polygenic D. codominant

Answer 1

A. Y-linked.

Explanation:

Males have one Y chromosome and one X chromosome, while females have two X chromosomes.

If the father is affected by a genetic disorder, that means it will be passed down to only sons in the family, not females, since females do not have a Y chromosome.

This would mean the genetic disorder is Y-linked, and only on the Y chromosome, which is specific to males.

Answer 2

Answer:

A. Y-linked

Explanation:

Males have one Y chromosome and one X chromosome.

Females have two X chromosomes.

Father is affected by a genetic disorder. The son has the same disease. The daughters are not affected because they do not have Y chromosomes.

The father and son have Y chromosomes, so the type of inheritance is Y-linked.
