In pea plants, t is the allele for tall plants, while t is the allele for dwarf plants. if you have a tall plant, demonstrate with a test cross how it could be determined if the plant is homozygous tall or heterozygous tall?

Explanation:since T- represent tallness

t-dwarf plant

TT- means the plant is homozygous tall i.e the allele T is the same 100% talk

Tt- means the plant is heterozygote tall which implied that though this plant express tallness its still have gene for shortness hidden in its cell and if crossed with a plant that is dwarf some of the offspring will be dwarf.

From the test cross all the gametes are heterozyote - Tt Tt Tt Tt
