What are the resultant phenotypes expected from a cross of GgAa x ggaa if the traits assort independently?

When crossing two organisms with genotypes GgAa and ggaa, where the traits assort independently, the expected offspring can be determined by examining the potential gametes produced by each parent and applying a Punnett square.

The parent with genotype GgAa can produce four types of gametes: GA, Ga, gA, and ga. The parent with genotype ggaa can produce only one type of gamete: ga. When these gametes combine, the resulting offspring's genotypes will vary based on the combinations of these gametes.

For each combination of gametes from the parents, we would get the following genotypes:

1. GgAa (from GA + ga)

2. Ggaa (from Ga + ga)

3. ggAa (from gA + ga)

4. ggaa (from ga + ga)

These genotypes correspond to different phenotypes based on the dominance of the traits involved. Since G and A are dominant traits over g and a, respectively, we can assess the phenotypic ratios derived from the combinations.

The phenotypic ratio resulting from these combinations, assuming independent assortment where each trait is considered separately, will lead to a distribution that reflects a ratio of 1:1:1:
