Question

ou make a Punnett square for a cross and find the results shown below.

A Punnett square is shown. The columns are labeled Upper X and x for male. The rows are labeled Upper X and x for female. Clockwise from upper left the boxes contain: Homozygous dominant, Heterozygous, Homozygous recessive, heterozygous.

Your prediction is that
of the offspring would have the dominant phenotype, and
of the offspring would have the recessive phenotype.

Answer 1

3/4 (75%) would show the dominant phenotype, and 1/4 (25%) would show the recessive phenotype.
