Question

can you explain the dihybrid cross where the two parents differde in two pairs of contrasting traits :seed color and seed shape?

Answer 1

Answer:

In other words, one parent is homozygous dominant and the other is homozygous recessive. As in a dihybrid cross, the F1 generation plants produced from a monohybrid cross are heterozygous and only the dominant phenotype is observed. The phenotypic ratio of the resulting F2 generation is 3:1

As an example, let's look at pea plants and say the two different traits we're examining are color and height.
