if individual 4 has an offspring with a male who does not have the trait what is the probability of having a daughter with the trait? type your answer... %

Explanation:

Step1: Identify parental genotypes

Individual 4: $X^F X^f$; Unaffected male: $X^f Y$

Step2: List daughter genotype possibilities

Daughters inherit father's $X^f$, and one of mother's X chromosomes: $X^F X^f$ (affected) or $X^f X^f$ (unaffected)

Step3: Calculate probability

Probability of affected daughter = $\frac{\text{Number of affected daughter genotypes}}{\text{Total daughter genotypes}} = \frac{1}{2} = 50\%$

Answer:

50
