Question

If the genotype ratio of the offspring here is 2 Hh: 2 hh, i.e., 1:1, what is the phenotype ratio?
A.
2:1
B.
1:1
C.
1:2
D.
3:0

Answer 1

B. 1:1

Explanation: If H is dominant, Hh individuals show the dominant phenotype and hh show the recessive phenotype. With 2 Hh and 2 hh, that's 2 dominant : 2 recessive → 1:1.
