You are examining heritability of traits implicated in disease resistance/avoidance in snails. Given the values below determine heritability.
Trait
VG
VE
VP
H2
A. Level of oxidative molecules in the blood
5.33
0.65
B. Phototaxis toward dark habitat, which reduces exposure to parasites
1.36
4.72
C. Presences of proteins implicated in parasite recognition in the blood
4.26
1.63
You are examining heritability of traits implicated in disease resistance/avoidance in snails. Given the heritability values you calculated above, which trait would you select for to increase the frequency of resistant snails in the fewest number of generations and why?
