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

Explanation:

Step1: Identify dominant - recessive traits

Green is dominant, yellow is recessive.

Step2: First - generation cross

When a yellow - pod (recessive) and green - pod (dominant) plant are crossed, the offspring (C) will show the dominant trait (green) if the green - pod parent is homozygous or heterozygous. Let's assume a simple cross. If the green - pod parent has at least one dominant allele, the first - generation offspring (C) will be green.

Step3: Second - generation cross

When C (green) is crossed with itself or another plant, since green is dominant, some of the second - generation offspring (D) will be green. Also, the original green - pod parent (A) has the green - pod trait.

Answer:

C. A, C, and D only
