Answer:
1.The pea plant is heterozygous for both seed shape and color, therefore, its genotype is SsYy. The possible gametes it can produce are SY, Sy, sY, and ss and each has an equal chance (25%) of being given by the pea plant to its offspring.
2.dihybrid cross,
Unlinked genes assort independently: This figure shows all possible combinations of offspring resulting from a dihybrid cross of pea plants that are heterozygous for the tall/dwarf and inflated/constricted alleles. Homologous chromosomes possess the same genes in the same linear order.
