Question

A farmer gets 72 plants after self pollination in F2 generation.How many are Tall plants and how many are short plants. Tallness is the dominant trait. There were 160 peaplants in a field after self pollination in Dihybrid variation.Find How many plants have Violet and White flowers round and wrinkled traits.White and round are dominant traits

Answer 1

Answer:

Explanation:

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.
