Different versions of a gene (Blue, Brown, Red)
The passing of genetic material from parents to offspring
All possible outcomes; a graphic used to predict the possible genotypes of offspring in a given genetic cross
What you can see; observable traits or physical features (brown hair, green eyes)
Combination of alleles that you inherit from your parents Bb, BB, bb...
Each allele in a hetero (Hh or bB) individual influences the phenotype (blue + yellow = green); Blends the two
