In Mendel's pea plant experiments,in order for him to have observed a 3:1 phenotypic ratio in the F₂ generation,which of the following must be true?

Question

Mendel's principle of segregation states that the two alleles of a gene separate during gamete formation, meaning that each gamete receives only one allele for each trait. This is necessary for the 3:1 phenotypic ratio observed in the F₂ generation, as it allows for the expression of both dominant and recessive traits in offspring. Choice B is not necessarily true, as heterozygous individuals can still produce the 3:1 phenotypic ratio if they carry one dominant and one recessive allele. Choice C is also not necessary, as long as the alleles segregate properly during gamete formation. Choice D is also not necessary, as even if the F₁ parents are not breed true, their alleles can still segregate properly in the F₂ generation.
