Question

Which of the following is true regarding sex limited traits?

Multiple Choice
a. They are always X-linked
b. They are phenotypically expressed in only one sex.
c. They are recessive in one sex and dominant in the other.
d. They do not exist.

Answer 1

Sex-limited traits are phenotypically expressed in only one sex.

Step-by-step explanation:

X-linked traits are traits that are located on the X chromosome. They are not always X-linked, as there are other genes on the X chromosome that are not sex limited.

Sex-limited traits are traits that are present in both sexes but expressed phenotypically in only one sex. This means that the two sexes show different traits or phenotypes. Therefore, the correct answer is b. They are phenotypically expressed in only one sex.
