Question

3:1 Monohybrid: :9:3:3​

Answer 1

Answer:

If both parents are heterogeneous for both traits the ratio of phenotypes is the ratio of 9:3:3:1. One trait is dominant and the other trait is recessive. Of the 16 possible offsprings only 1 will have both recessive genes. Only with double recessives will the phenotype show both recessives.
