Answer No 1)

For a trait to be homozygous dominant, both the alleles of a gene should be the same dominant ones. For example, lets consider black to be a dominant colour in pigs. In this scenario the genotype for homozygous dominant parent will be BB. A dominant trait is the one which can mask the effect of a recessive trait.

Answer No 2)

A recessive trait can be described as the trait which gets suppressed by the dominant trait. For example, lets consider red colour to be recessive in the pigs. In this case, the genotype of the homozygous recessive parent will be bb.

Answer No 3)

To determine the genotype of the offspring, lets make a punnet square:

        b           b

B     Bb         Bb

B     Bb         Bb

The colour of the offspring will be black as it was the dominant trait. The genotype will be heterozygous dominant i.e Bb.
