mendel discovered that the allele for green seed pods (g) is dominant to the allele for yellow seed pods (g). he crossed true-breeding (homozygous) parental plants with green (gg) and yellow (gg) seed pods to produce an f1 generation, all of which were heterozygous (gg) with green seed pods. he then crossed two of these f1 plants to produce an f2 generation. drag the genotypes and phenotypes from the left to correctly complete the punnett square for the f2 generation. labels may be used more than once.

The genotypes and phenotypes from the left to correctly complete the punnett square for the f2 generation are:

The Punnett square for the F2 generation:

G g

G GG Gg

g Gg gg

What is the Punnett square about?

In this Punnett square, G represents the dominant allele for green seed pods, and g represents the recessive allele for yellow seed pods. The F1 generation plants are heterozygous (GG), meaning that they have one dominant allele for green seed pods and one recessive allele for yellow seed pods.

When these plants are crossed, the F2 generation can have four possible genotypes: GG (homozygous dominant for green seed pods), Gg (heterozygous for green seed pods), gG (heterozygous for green seed pods), and gg (homozygous recessive for yellow seed pods).

The genotypes GG and Gg will produce plants with green seed pods (the dominant trait), while the genotypes gG and gg will produce plants with yellow seed pods (the recessive trait).

Therefore, the F2 generation will have 3 plants with green seed pods and 1 plant with yellow seed pods. The phenotypes in the F2 generation will be 75% green seed pods and 25% yellow seed pods.
