Phenotypes
= Physical traits that you can observe
Example:
Height
Blood type
Eye colour
Animal fur patterns

Writing and interpreting Genotypes
1. Figure out which allele is dominant and which one is recessive
2. Assign symbols for each trait: use a capital letter for dominant and a lower case for recessive
3. If the phenotype is purebred or homozygous, write two identical letter symbols.
4. If the phenotype is hybrid or heterozygous, write one large and one small letter symbol

The Goal:
By the end of this practice drill, you should be able to figure out genotypes for different traits,
and interpret phenotypes from given genotypes.
Let’s go!
