Know these terms:
Alleles are the letters that represent the traits that are present on our DNA. We have been studying traits that have only 2 alleles, one from Mom and one from Dad.
Homozygous means that the person has the exact same alleles (letters are both capitals or both lowercase)
Heterozygous means that the person has one capital and one lowercase
The stronger allele is called Dominant.
The weaker allele is called Recessive.
If there are two dominants then they might be co-dominant and therefore they average their trait such as tall and short becoming average sized. (This is a bonus on the quiz)
