Question

ln humans, red green color blindness is a sex-linked recessive trait. If a man and a woman produce a color blind son, which of the following must be true?

a. The father is color blind.
b. Both parents carry the allele for color blindness.
c. Neither parent carries the allele for color blindness.
d. The father carries the allele for color blindness.
e. The mother carries the allele for color blindness.​

Answer 1

B is the answer
If it’s a recessive allele 1 parent isn’t enough, both parents have to have the recessive allele, and even then it’s a small chance. Hope this helped ^^

Answer 2

If a man and a woman produce a color blind son then both parents carry

the allele for color blindness.

A trait could either be:

• Dominant

• Recessive

What is a Recessive trait?

A recessive trait is usually expressed when there is the presence of two

recessive alleles in an individual or organism. A dominant  trait on the other

hand can be expressed with the organism having only one dominant allele

In this scenario, the red green color is a recessive trait

and the offspring produced is color blind which basically means that both

parents carry the allele for color blindness.
