• Homozygous recessive

• dd

• Homozygous dominant

• DD

• Heterozygous

The genotypic percentage resulting from this this cross would be _____________________.

• 25% blue eye 75 % brown eye 
• BB = 25% Bb = 50% bb = 25%
• BB= 50 % bb = 50%
• All brown eye

What term describes what you see, or the physical appearance.

• Genotype
• Phenotype
• Homozygous
• Heterozygous
