Question

Three strains of green-seeded lentil plants appear to have the same phenotype. The strains are designated G₁, G₂, and G₃. Each green-seeded strain is crossed to a pure-breeding yellow-seeded strain designated Y. The F₁ of each cross are yellow; however, self-fertilization of F₁ plants produces F₂ with different proportions of yellow- and green-seeded plants as shown below.

For each set of F₂ progeny, provide a genetic explanation for the yellow : green ratio. What are the genotypes of yellow and green F₂ lentil plants in the G₂ x Y cross?

For each set of F₂ progeny, provide a genetic explanation for the yellow : green ratio. What are the genotypes of yellow and green F₂ lentil plants in the G₂ x Y cross?

Accepted Answer

Hey, everyone. Let's take a look at this question together in which of the following episodic interaction, both genes are required for the correct phenotype. So let's recall what we've learned about episodic interactions to determine which of the following requires both genes in order to display the correct phenotype. So when we say that both genes are required for the correct phenotype, we are saying that both jeans work together to express a single being a type. And so looking at the following episodic interactions, which one describes a case in which both genes work together to express a single phenotype. And we know that it is answer choice b complementary gene interaction because we know that complimentary gene interaction involves complementary genes that work together to produce a specific phenotype within a person. So answer choice B complementary gene interaction is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
