If 2 heterozygous pea plants with yellow round seeds are crossed, what is the ratio of the yellow round seed?

If two heterozygous pea plants are crossed with yellow round seeds, the resulting progeny mostly show the dominant phenotype.

Explanation:

Plants with two different alleles of a gene are heterozygous. As all the heterozygous offspring are yellow, then the yellow allele must be dominant over the recessive green allele.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
