which allele combination represents a female who is heterozygous for a sex - linked trait?\no $x^{r}y$\no $x^{r}y$\no $x^{r}x^{r}$\no $x^{r}x^{r}$

C. $X^{R}X^{r}$

Brief Explanation:

Females have XX chromosomes. Heterozygous means having two different alleles. $X^{R}X^{r}$ fits this for a sex - linked trait.
