Answer

B. 50\% Explanation 1. Identify Alleles The mother has one allele for color blindness (X\textsuperscript{c}) and one for normal vision (X). 2. Determine Gamete Probability Each gamete receives one of the two alleles. Thus, the probability of a gamete having the allele for color blindness is **50%**.
