Question

Jacob cross-pollinates a true breeding pea plant that has yellow pea pods with

a true breeding pea plant that has green pea pods. All of the offspring have
green pea pods. Which allele is dominant and which is recessive? What alleles
do the green F1 generation plants have?

Answer 1

Answer: The green allele is dominant. The F1 generation has one yellow allele and one green allele.

Step-by-step explanation:

The P generation had to pass down a yellow and green allele from each of the true-breeding (pure-bred) plants. If green is the trait being seen, even though the yellow allele is present, green is dominant. The F1 generation has one of each allele.
