Question

Pattern baldness in males is a trait found on the "x" s*x chromosome (pair 23). Which of the following is a true statement?

A. If a boys father is bald, he has a fifty percent chance of also being bald.

B. Baldness can only be inherited from the mother.

C. All males have a twenty-five percent chance of inheriting pattern baldness.

D. none of the above

I think its C..am I right?

Answer 1

B. Baldness can only be inherited from the mother.

Answer 2

remember that individuals inherit one copy of a chromosome from each parent

males are genetically XY and must inherit their Y chromosome from their father.

since baldness is on the X chromosome, and a male can only inherit his X from his mom, that leaves you with answer B.

Answer 3

Your answer is B. Pices318 nailed it

Answer 4

Y comes from dad and X comes from mom. Two X chromosomes to chose from. One thing you are forgetting is that it can be a 50% chance OR 100% chance as well. The female mother can have inherited two baldness X chromosomes from her mother and father. Hence guaranteeing that the child *has* to be bald. :o
