which allele combination represents a female who is heterozygous for a sex - linked trait?\n○ $x^{r}y$\n○ $x^{r}y$\n○ $x^{r}x^{r}$\n○ $x^{r}x^{r}$

Answer

Brief Explanations:

Females have XX sex - chromosomes. A heterozygous individual has two different alleles for a trait. For a sex - linked trait in females, the heterozygous combination would be one dominant allele ($X^R$) and one recessive allele ($X^r$).

Answer:

C. $X^RX^r$
