Question

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.
In which squares should the phrase “Green pods” appear?

1.A and D
2.B and E
3.A,C and D
4.A,B,C,D and E

Answer 1

The correct answer is 3. A, C and D

Square labels  A, C and D are to be marked as "green pods."

According to Mendel’s laws of inheritance, when a plant with dominant trait is crossed with plant with recessive trait, as a result dominant phenotype is appeared in all the F1 offspring. On Selfing F1 offspring, produces F2 offspring with dominant and recessive trait. In the given scenario, pea plant with ‘green pods’ are dominant and pea plant with ‘yellow pods’ is recessive.  Therefore, when pea plant with green pod is crossed with pea plant with yellow pods, the F1 offspring (C) produced are with green pods. Thus, parent (A) is with green pods and F2 offspring (D) is with green pods.
