Which of the following is true for a sex- influenced trait?a)expressio...
Sex-influenced traits are traits that are influenced by the sex of an individual. These traits are not limited to any one sex and can be expressed in both males and females. They are also influenced by the hormone constitution of the person. Therefore, options A, B, and C are true for sex-influenced traits.
Let's break down each of these options in detail:
a) Expression of a phenotype is not limited to any one sex:
This means that the trait can be seen in both males and females. For example, pattern baldness is a sex-influenced trait. While it is more commonly observed in males, females can also exhibit this trait. Therefore, the expression of the phenotype is not limited to any one sex.
b) It can be expressed in both males and females:
As mentioned above, sex-influenced traits can be expressed in both males and females. The expression of these traits may vary between the sexes due to differences in hormone levels or other genetic factors. For example, certain types of hair loss may be triggered by the presence of high levels of androgens, which are more commonly found in males. However, females with high androgen levels can also experience this trait.
c) It is influenced by the hormone constitution of the person:
Hormones play a crucial role in the expression of sex-influenced traits. The hormone constitution of an individual, which includes the levels of various hormones such as androgens and estrogens, can influence the expression of these traits. For example, the presence of high levels of androgens can lead to the development of facial hair in both males and females.
In conclusion, sex-influenced traits are not limited to any one sex, can be expressed in both males and females, and are influenced by the hormone constitution of the person. Therefore, options A, B, and C are all true for sex-influenced traits.
