which allele combination represents a male who has an x - linked recessive disorder?\no $x^{r}y$\no $x^{r}y$\no $x^{r}x^{r}$\no $x^{r}x^{r}$

which allele combination represents a male who has an x - linked recessive disorder?\no $x^{r}y$\no $x^{r}y$\no $x^{r}x^{r}$\no $x^{r}x^{r}$

Answer

Brief Explanations:

Males have XY sex - chromosomes. In X - linked recessive disorders, a male only needs one copy of the recessive allele on his single X - chromosome to have the disorder. The recessive allele is represented by a lowercase letter. So, the combination is $X^rY$.

Answer:

$X^rY$
