Making F1 Hybrids
Hypothesis
stock1
Stock#1 		X stock2
Stock#2
The dominant allele is:
The genotype of Stock #1 is:   X   The genotype of Stock #2 is:

Prediction If this hypothesis is true, when we cross the two stocks described here, then we should find progeny as shown in the Punnett Square:
Stock #2 Gametes
Stock #1
