Genotype: What the genes are- the list of the rabbit’s loci and alleles. Genotype is typically displayed in a series of letters that represents the genes that create the color and pattern of a rabbit. These letters tell us what the rabbit will look like. For example, a chestnut (wild color) rabbit’s genotype might be Aa Bb CC Dd Ee. More on what each of these letters means as we go along.
Phenotype: What you SEE visually on the rabbit. The chestnut rabbit above has a simpler PHENOTYPE than GENOTYPE. The genotype is Aa Bb CC Dd Ee, but the phenotype is chestnut.

PUNNETT SQUARESPunnett Squares are SUPER useful tools! They are a square diagram that is composed of a grid of usually four boxes and is used to calculate and depict all the combinations and frequencies of the different genotypes and phenotypes among the offspring of a cross. Note: Each result represents the possibility for each kit, not for the whole litter.
We will dive further into Punnett Squares later in the lessons. |
