2. Genotype vs Phenotype Genotype Phenotype
The alleles that an organism has for a particular trait.
Example: AA, Aa, aa
Phenotype
The observable traits of an organism.
Brown and blue eyes are phenotypes.

3. Homozygous vs Heterozygous
Homozygous: a genotype in which both alleles are the same
AA or aa
Heterozygous: a genotype in which the alleles are different Aa

4. Punnett Square
A tool used to visualize all the possible combinations of alleles from the parents.

5. Making a Punnett Square Is One Way to Determine Likely Outcome of Genetic Cross

6. How to make a Punnett Square
Draw a square and divide it into four sections
Write the letters that represent alleles from one parent along the top of the box
Write the letters that represent alleles from the other parent along the side of the box
To make the cross bring one allele down and one over so that each of the four squares has now 2 alleles showing the genotypes that are possible with the cross
