Answer:

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

Step-by-step 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.
