Which represents the cross between parent plants if one is heterozygous for yellow-colored pods and the other is homozygous for green-colored pods?
a)yy x yy
b)yy x yy
c)yy xyy
d)yy xyy

The correct answer would be A)Yy x yy .

Genotypes can be of three types based on the types of alleles present:

Now, in heterozygous condition (Yy) the color of the pods is green. Hence, it must be the dominant character which is coded by allele "Y". Similarly, the green-colored pod is a recessive trait which is coded by "y" when present in homozygous condition.

Thus, the cross between heterozygous yellow-colored pods and green colored pods can be represented by Yy x yy.

The cross between parent plants if one is heterozygous for yellow-colored pods and the other is homozygous for green-colored pods is Yy x yy.

Further Explanation:

Genotypes help in the genetic makeup of any individual. Phenotype describes as a physical characteristic of an individual. The genotype is responsible for the phenotypes of any individual. If two copies of the same alleles present in an organism, its genotype is called homozygous. If two copies of different alleles present in an organism, its genotype is called heterozygous.

When a homozygous dominant individual is crossed with the homozygous recessive individual the resultant offspring has the genotype which is heterozygous and phenotype which is dominant. All possible genotypes of the parent as well as offspring are graphically represented in a Punnett square.

When the parent homozygous green pod having a genotype yy is crossed with the parent heterozygous yellow pod having a genotype of Yy. The resultant offspring of filial generation tends to be 50 percent of Yy which means heterozygous and 50 percent yy which means homozygous.
