A trait whose expression is affected by the presence of sex hormones is said to be
a. sex-influenced
b. sex-linked
c. X-linked
d. Y-linked
I read the section multiple tmes, and the book doesn't really specify. Thanks in advance if you could answer it!
"D" Y-Linked because a certain opening of the organs, if you are taking the class you should recognize the shape!
Nice helping someone of my knowledge!

I would disagree with Lori. The last three refer solely to genetic factors, but A allows for other factors including hormones.

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps a little more. Thanks for asking.
sex linked
To determine the correct answer, we need to understand the definitions of the given terms.
a. Sex-influenced: A trait whose expression is influenced by the sex of the individual. It means that the same gene is expressed differently based on whether an individual is male or female. For example, baldness is a sex-influenced trait, where the baldness allele is expressed more frequently in males.
b. Sex-linked: A trait that is controlled by genes located on the sex chromosomes, which are the X and Y chromosomes. Generally, sex-linked traits refer to genes located on the X chromosome, as there are fewer genes on the Y chromosome. Traits that are located on the X chromosome are inherited differently in males and females.
c. X-linked: This term specifically refers to traits that are determined by genes located on the X chromosome. Because males have only one X chromosome, they are more likely to exhibit X-linked traits because if they carry a recessive allele on their X chromosome, they do not have a second X chromosome to mask its expression. Hemophilia and color blindness are examples of X-linked traits.
d. Y-linked: This term refers to traits that are determined by genes located on the Y chromosome. Since the Y chromosome is only present in males, Y-linked traits are exclusively expressed in males. Examples of Y-linked traits include male-pattern baldness and Y-linked infertility.
Based on the given definitions, the correct answer to the question should be c. X-linked, as it describes traits that are influenced by the genes located on the X chromosome.
