Two diheterozygous pea plants with yellow smooth seeds were crossed. Determine the ratio of phenotypes of first-generation hybrids

This is Mendel’s third law – independent splitting of characters in the case of dihybrid crosses. Cleavage is formed according to the phenotype 9: 3: 3: 1. 9 yellow smooth: 3 yellow wrinkled: 3 green smooth: 1 green wrinkled
