Question

In the peas plants the allele for green pod color (g) dominates the allele for yellow pod color (g).The punnet square illustrates a cross for this trait.Which offspring can be described by these genotypes and phenotypes?

G G g

g GG Gg

g Gg gg

GG=

A.Homozygous offspring with yellow pod color

B.Homozygous offspring with green pod color

C.heterozygous offspring with yellow pod color

gg=

A.Homozygous offspring with yellow pod color or

B.Homozygous offspring with green pod color

C.heterozygous offspring with yellow pod color

Answer 1

GG-b

gg-a

Step-by-step explanation:

Answer 2

GG= B. Homozygous offspring with green pod color

gg= A. Homozygous offspring with yellow pod color

Step-by-step explanation:

According to the given information, the allele for the green pod color (G) is dominant over the allele for the yellow pod color (g). A genotype that has two identical alleles for a gene is called homozygous for the gene. On the other hand, the genotype that has one dominant and one recessive allele for a gene is heterozygous for the gene.

The genotype "GG" has two identical alleles for the gene of pod color. Hence, the offspring would be homozygous with green pods.

The genotype "gg" also has two identical alleles for pod color. But here, the alleles are recessive. Hence, the offspring would be homozygous with yellow pods.
