aleksley [76]

Answer:

True

Explanation:

Let the allele for green color of pods be G

and the allele for yellow color of pods be g

Phenotype of true breeding parent with green colored seeds is GG

Phenotype of true breeding parent with yellow colored seeds is gg

In F1 cross

GG mates with gg

Genotype of offspring - Gg

Phenotype of offspring - Green seed

Since the offspring has both the allele for green and yellow seeds color but yet only green is expressed. This indicate that green allele dominated the expression of yellow allele thus, it can be concluded that green seed pods were dominant over yellow seed pods.
