A pea plant that is homozygous for yellow pods with wrinkled seeds (ggrr) is cross-bred with a pea plant that is heterozygous fo
r green pods with round seeds (ggrr). how many different genotypes will the offspring of these parents have? what percentage of offspring will have each genotype?
1 answer:
The correct genotypes of the parents are ggrr for yellow pods with wrinkled seeds and GgRr for <span>heterozygous for green pods with round seeds.
If the heterozygous individuals for both traits express have green pods and round seeds that tells us that these traits are dominant.
In the gross presented below, you can see that the offspring will have 4 different genotypes, all present in an equal percentage:
</span><span>gGrR 25%
</span><span>gGrr </span>25%
<span>ggrR 25%
</span><span>ggrr 25%</span>
