Answer #1

Answer e.

Phenotype means the physical characteristics of a particular trait in an organism Example. Height, eye color, hair colour etc

Given that father is Homozygous dominant.

Let us consider the trait Height

So the genotype of Father is TT and the phenotype will be Tall

Mother is heterozygous means her genotype jas a recessive allele. Her gentype is Tt so phenotype is Tall (a recessive trait is presented only when the genotype is homozygous recessive)

By using the Punett square we get

Father Mother T t
T TT TT
T Tt Tt

The the genotype of Offspring is TT, Tt so the phenotype is Tall. Hence no recessive phenotype in offspring
