in mendel's monohybrid cross involving tall and short plants 500 seeds were produced in F2 generation How many seeds would produce tall plants with genotype TT
Answers
Explanation:
Each dihybrid plant produces 4 gamete types of equal frequency. in the offspring. F2 showed 4 different phenotypes: the round and yellow traits did not stay linked to each other. Ratios for each trait corresponds to what one would expect from monohybrid crosses.
In the resulting F2 generation, 3/4 showed the dominant phenotype, and 1/4 showed the recessive phenotype. For example, when a round seed line was crossed to a wrinkled seed line, the F1 generation was all round, and the F2 generation showed a phenotypic ratio of 3 round : 1 wrinkled.
Phenotypic ratio of Mendel's monohybrid cross is 3 : 1. A monohybrid cross is a cross between two plants with different variations at one genetic trait. Phenotypic ratio in monohybrid cross is - Tall : Dwarf = 3 : 1.
Answer:
125 seeds will produce genotype (TT)
Explanation:
as we know when mendel did the exprement the outcome was in a ratio of 1:2:1 by using the punet square we can find that there are TT-1 , Tt-2,tt-1 so therefore if we divide 500 in ratio of 1:2:1 we get TT-125 Tt-250 tt-125
