what is the probability that a female offspring of the cross that is shown above would have a recessive allele for duchenne muscular dystrophy disorder?\n0 percent\n25 percent\n50 percent\n100 percent

Answer

Explanation:

Step1: Analyze female offspring genotypes

Female offspring have XX chromosomes. From the Punnett - square, the possible genotypes for female offspring are $X^{M}X^{M}$, $X^{M}X^{m}$, $X^{M}X^{M}$, $X^{M}X^{m}$.

Step2: Calculate probability

Out of the 2 possible female - offspring genotypes ($X^{M}X^{M}$ and $X^{M}X^{m}$), 2 out of 2 female genotypes have the recessive allele $X^{m}$ at least once. The probability is calculated as $\frac{2}{2}=1$ or 100%.

Answer:

100 percent
