Answer 1

I hope you have understood

Answer 2

Answer:

The genotype of parents will be: WW (homozygous dominant) and ww (homozygous recessive).

Explanation:

• An experiment known as a test-cross involves determining the genotype of an organism that is displaying dominance for a particular trait.
• An organism may be homozygous or heterozygous for a trait when it manifests a dominant trait.
• The genotype of the organism can be determined using the homozygous recessive organism.
• The condition clearly shows that when an organism has homozygous dominant genotype, all of its progeny from test crosses will exhibit the dominant phenotype.
• If the organism's genotype is heterozygous, then half of the test cross's offspring will have a dominant trait, while the other half will have a recessive trait. ​
