In pea plants, the allele t encodes for tall plants, while the allele t encodes for dwarf plants. if a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant what are the expected genotypes of the offspring?

Tall (Tt).

Explanation:

Mendel has explained the laws of genetics and is also known as the father of genetics. Mendel explained the law of independent assortment, concept of dominance and law of segregation.

The cross has been done between the tall plant ( TT) and the dwarf plant (tt) the genotype of the offspring is Tt ( all tall plants). Their cross can be shown as follows:

Parent     TT         ×      tt

Gamete      T         ×      t

F1 generation      Tt ( all tall plants).

Thus, the plant genotype is Tt.
