1. Genotype and Phenotype

2. Genotype - The actual gene makeup of an organism
Genotype - The letters you’re made up of
Ex: - Hh or HH or hh

3. It is made up of two alleles, one from each parent
It’s got two letters, one from Mom and one from Pop

4. Homozygous (Purebred)
Both alleles are the same
Both capital or both lowercase letters
Example - GG or gg

5. Heterozygous (Hybrid)
Alleles are different
One capital and one lowercase
Example - Gg

6. Phenotype- The physical characteristics of an organism
It’s what you look like
Example - Tall, brown hair, …

7. If there is one or more dominant letter in the Genotype, that is what your phenotype will be
If there’s a capital letter, then you’ll look like what the capital letter stands for

8. If capital T stands for tall then
Example
If capital T stands for tall then
Genotype Phenotype
