Question

The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. In this cross, tallness (H) is dominant to shortness (h).

A Punnett square is shown. The columns are labeled Upper D and Upper H. The rows are labeled h and h. Clockwise from upper left the boxes contain: Upper H h, Upper H h, Upper H h, Upper H h.

Based on the Punnett square, what is the phenotype of the offspring?
Hh
HH
tall
short

Answer 1

tall

All four offspring are Hh (carry one dominant H), and since H is dominant, the phenotype is tall.
