Question

Give the genotypic and phenotypic ratios of F1 generation, when a hybrid tall pea plant(TT) is crossed with a pure dwarf pea plant(tt)​

Answer 1

Answer:

Mendel crossed pure tall plant(TT) with a pure dwarf plant(tt). In the F1 generation, tall plants are formed(Tt). When F1 plant is subjected to self pollination, in the F2 generation, 3 tall plants and 1 dwarf plants are formed. In the one homozygous tall plant (TT), 2 heterozygous tall plants(Tt), one homozygous dwarf plant(tt) are formed. Phenotypic ratio is 3:1, genotypic ratio is 1:2:1.

Answer 2

Answer:

phenotypic ratio is 3:1and genotypic ratio is 1:2:1
