Gender Controlled Trait

Sex-controlled traits are phenotypic traits that are expressed differently in individuals of different sexes. These traits may be caused by genes present in the genotypes of both sexes, but they may be expressed differently depending on the sex.

An example of such a characteristic would be hair color. People with dark hair color have genes responsible for hair color present in their genotype. However, these genes may be expressed differently in men and women. For example, men may have darker hair, while women may have lighter hair. This is explained by the fact that the genotype of men contains genes responsible for the production of testosterone, which can affect hair color.

Another example is body size. In some animals, such as giraffes, body size depends on the presence of genes that control growth. However, these genes are expressed differently in females and males. Male giraffes usually have larger body sizes than females. This is explained by the presence in the genotype of males of genes responsible for the production of testosterone.

Thus, sex-controlled traits are an important aspect of genetics and evolution because they can influence the survival and reproduction of species. Understanding these traits can help scientists and biologists better understand evolutionary processes and develop new treatments for sex-linked diseases.



Sex-controlled traits are traits determined by the genes present in the genotype of males, but manifest themselves differently in female and male individuals. Traits controlled by species and sex in an organism are called species traits. They are clearly manifested in karyotypes - special formations found inside each cell of an organization.
