Question

Determine whether the following scenarios are sex-linked, sex-limited or sex-influenced: " Pattern baldness occurs in males with just one copy of the baldness gene. Females, however, will only express the baldness gene if homozygous for the autosomal gene.

Answer 1

Pattern baldness is a sex-influenced trait that occurs in males with one copy of the gene. Females need to be homozygous for the autosomal gene to express the baldness gene.

Step-by-step explanation:

Pattern baldness is an example of a sex-influenced trait. It occurs in males with just one copy of the baldness gene. Females, on the other hand, will only express the baldness gene if they are homozygous for the autosomal gene.

In this case, the baldness gene is not located on the sex chromosomes, but its expression is influenced by the presence of sex hormones. The hormone testosterone can trigger the expression of the baldness gene, which is why males with only one copy of the gene can still develop pattern baldness.
