Answered

in pea plants, the gene for round seed (r) is dominant and wrinkled seeds (r) are recessive. the endosperm of the pea is also either starchy, a dominant gene (s) or waxy (s). what can be said of a fully heterozygous dihybrid cross?



Answer :

In a dihybrid cross, all of these options are potential combinations.

What genotype does a pea plant have if the round seeds are heterozygous recessive and the green seeds are homozygous recessive?

RrYy is the genotype of a plant pea with heterozygous round seeds and homozygous recessive green seeds. A dihybrid cross's starting genotype would be RrYy and RrYy.

The pea wrinkled seed allele is a recessive allele, so why?

Garden peas' gene for wrinkled seed shape is regarded as recessive because heterozygotes do not express the characteristic it is linked to. Heterozygotes are people with two distinct alleles at the same gene locus.
