Answer:
Explanation:
The genotypes in the offspring of the p-generation, i.e. F1, are
Hh (hetero-zygous) short hair
hh (homo-zygous) long hair
each with 50%
However, when Hh crosses with hh, the proportion of the F1 should be 50% each of long and short hair. The diagram shown does not seem to be consistent with realigy.
