Question

what is the probability of the offspring having hemophilia for the cross that is shown in the punnett square? 50 percent 75 percent

Explanation:

Step1: Analyze Punnett Square

The Punnett square has 4 cells (offspring genotypes): \(X^H X^h\), \(X^H Y\), \(X^h X^h\), \(X^h Y\).

Step2: Identify Hemophilia Genotypes

Hemophilia (X - linked recessive) occurs in \(X^h X^h\) (female) and \(X^h Y\) (male). Count these: 2 out of 4.

Step3: Calculate Probability

Probability = \(\frac{2}{4} = 0.5\) or 50%.

Answer:

50 percent
