The gene for tall (T) is dominant over the dwarf (t) in the garden Pea plant use by Mendel. A P plant that comes from a line of true breeding tall plants is crossed with a dwarf Pea plant. What are the phenotypes and genotypes of the F1 generation

Verified Answer :

Parentals - TT x tt. 
F1 generation : 
        - Genotypes = All Tt (Because all inherit  'T' from parent 1 and 't' from parent 2). 
        - Phenotypes = All Tall (Because the Tall trait is completely dominant to dwarf.

The phenotypes of the F1 generation are all tall plants.

The genotypes of the F1 generation are all heterozygous for tall plants.

Mendel's theory helps us to understand the fundamental laws of inheritance and how genes are been transferred from parents to offspring.

From the information given:

  • The gene of a dominant tall garden pea = T
  • The gene of a recessive dwarf garden pea = t

A plant of a true-breeding tall plant (TT) is crossed with a dwarf pea plant tt.

The crossing of the first filial generation F1 can be explained by using the Punnett square:

      T        T

t      Tt     Tt

t       Tt     Tt

  • The phenotypes of the F1 generation are all tall plants.
  • The genotypes of the F1 generation are all heterozygous for tall plants.
