In a Mendelian monohybrid cross, the F2 generation shows identical genotypic and phenotypic ratios. What does it tell us about the nature of alleles involved? Justify your answer.
Answers (1)
The alleles segregate and go to each of the parents when plants of F1 generation reproduce without the cross. The segregation is random with equal probability of a particular allele going to either of the parental gametes. Thus, genotype and phenotype in the F2 generation are identical. So, there will be 50% of plants with pure genotype and 50% of plants with mixed genotype.
