And

What are the two types of homozygous genotypes
Dominant and Recessive
The tool used to show the probability of a specific trait showing up in the offspring.
Punnet square
When each allele shows a degree of influence on the trait
Incomplete dominance
Neither trait is more or less dominant
Co- dominance
