Question

look at the punnett square for an x - linked recessive disease. is it possible for a female offspring to have the disease? yes no

Explanation:

In X - linked recessive inheritance, females have two X chromosomes (\(X^{r}X^{r}\) would be the genotype for a female with the disease). Looking at the Punnett square, if the father has \(X^{r}Y\) (assuming \(X^{r}\) is the recessive disease - carrying X chromosome) and the mother has \(X^{r}X^{r}\), then female offspring can get \(X^{r}\) from both parents.

Answer:

yes
