Question

In the pea plant, the allele for green pod color (G) dominates the allele for the yellow pod color (g). The Punnet square illustrates a cross for this trait. Which offspring can be described by these genotypes and phenotypes?

Answer 1

the color of the pea pods will be have a more of a chance to be green due to the fact that there is 75% of the square, because the big G means that it will be that color and if it has (gg) then it will be yellow.

Answer 2

a) Homozygous offspring with yellow pod color - gg

b) Homozygous offspring with green pod color - GG

c) Heterozygous offspring with yellow pod color - None

Step-by-step explanation:

It is given that green pod color (G) is dominant over yellow pod color (g).

Thus, an offspring will have green pod color, when its has heterozygous genotype (Gg) and homozygous dominant genotype (gg). While an offspring will have yellow pod color, only when it has homozygous recessive genotype (gg).

Thus, the offspring with under given phenotypes will have following genotypes -

a) Homozygous offspring with yellow pod color - gg

b) Homozygous offspring with green pod color - GG

c) Heterozygous offspring with yellow pod color - None , a heterogygous offspring will be green in color as green pod color is dominant over yellow pod color.
