B = allele for short fingers (dominant)
b = allele for normal fingers (recessive)
G = allele for the ability to blow large bubbles from bubble gum (dominant)
g = allele for the lack of ability to blow large bubbles from bubble gum (recessive)
Determine all possible genotypes of the offspring of these parents:
Mother: doubly homozygous for short fingers and ability to blow large bubbles
Father: normal fingers with no ability to blow large bubbles
