Question

What would be the expected phenotypic and phenotypic ratio of the F2 generation?

Mendelian Inheritance in Plants Study Questions t law of equal segregation of alleles into the gametes during meiosis. A monohybrid cross is used to determine the inheritance pattern of a single trait. Two pure breeding parents were crossed and then the F1 progen crossed to produce the F2 generation. One parent was homozygous dominant for the trait and the other parent was homozygous recessive for the same trait. The trait exhibits complete dominance. There is equal segregation of alleles into the gametes during y were meiosIS What would be the expected phenotypic ratio of the F2 generation? What would be the expected genotypic ratio of the F2 generation? Represent the gene with the letter"A". Use a capital letter to denote the dominant allele and the lower case letter to signify the recessive allele.

Explanation / Answer

AA is homozygous dominant nature. Whereas aa is homozygous recessive trait. Due to meiosis, they produce gametes. Upon fusion of gametes it gives F1 Progeny . The F1 Progeny is Hetetozygous in nature (As). Self cross between F1Individuals produce F2 Progeny. The phenotype ratio of F2 progeny is 3:1. Genotype ratio of F2 Progeny is 1:2:1
