Explain with an example the inheritance of the dihybrid cross. How is it different from monohybrid cross?
In pea plants, yellow seeds are dominant to green. If a heterozygous yellow seed pant is crossed with a green seeded plant, what ratio of yellow and green seeded plants would you expect in the F1 generation?
In a dihybrid cross, if you get 9:3:3:1 ratio it denotes that ______.

Two pea plants - one with round yellow seeds (RRYY) and another with wrinkled green (rryy) seeds produce F1 progeny that have round, yellow (RrYy) seeds.
