Question

In four o'clock plants, many flower colors are observed. In a cross involving two true-breeding strains, one crimson and the other white, all of the F₁ generation were rose color. In the F₂, four new phenotypes appeared along with the P₁ and F₁ parental colors. The following ratio was obtained:

1/16 crimson 4/16 rose
2/16 orange 2/16 pale yellow
1/16 yellow 4/16 white
2/16 magenta

Propose an explanation for the inheritance of these flower colors.

Accepted Answer

Hello everyone and welcome to today's video. So in Mendel's experiment, he selected contrasting pairs of traits to be studied after making the parental generation. What he observed in the F. One results. The key to solving this problem is going to be here in this phrase, contrasting pairs. What this means is that he selected the homicidal dominant and the homosexuals recessive gina types. Well we're going to assign the homicidal dominant, the following genotype and the homicidal recessive, the following genotype. And he made this too. He combined the parental generation to obtain the F. One generation. We're going to make this or we're going to create this cross using opponent square to see what he observed in the F. One generation. And if we create this pony square, we're going to realize that everyone in the F. One generation is going to be heterosexual. And if we know something about these heterocyclic organisms is that they're going to displace or display their dominant peanut type. So all of these individuals in the F. One generation. In Mendel's experiment were displaying the dominant phenotype, which is what he observed because of this. The correct answer choice is going to be answer choice. B all had dominant phenotype. I really hope this video helped you and I hope to see you on the next one
