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? a and d only b and e only a, c, and d only a, b, c, d, and e

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? a and d only b and e only a, c, and d only a, b, c, d, and e

Answer

Explanation:

Step1: Understand dominant - recessive traits

Let the allele for green pods be (G) (dominant) and for yellow pods be (g) (recessive). A cross between a yellow - podded plant ((gg)) and a green - podded plant ((GG) or (Gg)) is made. If the green - podded plant is (GG), all the first - generation offspring ((C)) will be (Gg) (green pods) because of the dominance of the green - pod allele.

Step2: Analyze first - generation cross

When the first - generation offspring ((C), which is (Gg)) self - crosses, the possible genotypes of the second - generation offspring ((D) and (E)) are (GG:Gg:gg) in a ratio of (1:2:1). The genotypes (GG) and (Gg) will have green pods.

Step3: Determine the squares with green pods

Since green pods are dominant, if (A) is the green - podded parent (either (GG) or (Gg)), (C) (the first - generation offspring which is at least (Gg)) and the green - podded second - generation offspring ((D) if it has (G) allele) will show the green - pod trait. So the squares where “Green pods” should appear are (A), (C), and (D) only.

Answer:

C. A, C, and D only
