Punnett Square Analysis

The ratio of heterozygous, homozygous, and hemizygous in offspring can be determined through a Punnett square analysis. In this case, the husband is color blind, meaning he has an X-linked recessive condition. The wife is a carrier, meaning she has one normal X chromosome and one X chromosome with the color blind allele.

The Punnett square for this cross would be as follows:

| | Xc | Xc |
|---|----|----|
| Y | XcY| XcY|
| Y | XY| XY|

The offspring will have two possible genotypes: XcY (heterozygous) or XY (normal). The ratio of heterozygous to normal offspring is 1:1, as each of the four squares in the Punnett square has an equal chance of occurring.

There will be no hemizygous offspring in this cross, as hemizygosity refers to the presence of only one allele in a diploid organism. In this case, males will inherit only one X chromosome from their mother and will therefore be either color blind or normal, depending on which X chromosome they inherit. Females will inherit two X chromosomes, one from each parent, and can be either normal, carriers, or color blind.

Therefore, the correct ratio of heterozygous to homozygous to hemizygous offspring in this cross is 1:1:0, which can be simplified to 1:1.
