Answer:
a: 1/4
b: 1/2
c: 1/4
d: 0
Explanation:
Since the wife had a color-blind father (X^cY), she should be a carrier for the disease. Her genotype would be "X^cX". Fathers do not transmit the X-linked disorders to their sons, so the genotype of the husband is "XY".
a. The probability that the couple's first child will be a normal son: 1/4
b. The probability that the couple's first child will be a normal daughter: 1/2
c. The probability that the couple's first child will be a color-blind son: 1/4
d. The probability that the couple's first child will be a color-blind daughter: Zero

The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy., i.e., option A.
<h3>What is heterozygous?</h3>
The occurrence of different types of alleles is referred to as heterozygous condition.
A heterozygous genotype may consist of one normal allele and one mutated allele, or two distinct mutated alleles.
The missing options of the question are:
- Yy ´ yy
- YY ´ yy
- Yy ´ Yy
- yy ´ yy
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy.
Thus, the correct option is A.
