Technician A says that the front brakes do most of the braking because the front brakes are larger. Technician B says that due to weight transfer, most of the braking force needs to be done by the front brakes. Which technician is correct?

The offspring is homozygous for hair types.

Explanation:

Humans contain 23 pairs of chromosomes. The offspring inherits half chromosome from the father and half chromosome from the mother and becomes diploid cell.

Homozygous represents the same allele of a particular trait. In the given diagram, the offspring is homozygous for eye color as the alleles are identical for eye color.

Thus, the correct answer is option (4).
