Round pea allele R is dominant to wrinkled pea allele r, while yellow pea allele Y is dominant to green pea allele y. Homozygous
allsm [11]

Answer:

RrYy (F1 generation)

Explanation:

This is a typical dihybrid cross involving two genes in the pea plant; one coding for seed colour and the other for seed shape.

According to Mendel's law of dominance, an allele is capable of masking another allele in a gene, the allele that masks or is expressed is called the DOMINANT allele while the allele being masked is called RECESSIVE allele.

Homozygosity of a gene refers to it having the same type of alleles while heterozygosity refers to having different alleles.

In this example, allele for Round (R) and Yellow (Y) pea is dominant over the allele for Wrinkled (r) and green pea respectively.

Homozygous round green pea (RRyy) crossed with Homozygous wrinkled yellow (rrYY) will give rise to a heterozygous round yellow (RrYy) F1 offsprings.
