Question

Given that green pea pods are dominant over yellow pods , cross two heterozygous green plants

Answer 1

Answer:

When Two heterozygous plants with Green Pod are crossed

The phenotype ratio of Green pod: yellow pod Plant = 3:1

The Genotype ratio is 2:1:1

Explanation:

Observe the Punnett's Square in the attachment:

• Heterozygous individual has two different alleles of the same gene one of which is diominant and the other is recessive.
• When Heterozygous Individual's cell undergoes meiosis the two alleles segregate and each gamete recieves either of the alleles.
• When two heterozygous plants are crossed there are chances that Gametes with  dominant alleles fuse producing a homozygous dominant (YY), a gamete with dominant allele fuses with a gamete having recessive allele producing a Heterozygous (Yy) individual showing dominant trait or a gamete with recessive allele fuses to produce a homozygous recessive (yy).
