POPULATION GENETICS
Mendelian Genetics
- Monk in what is now Czech r
-8 years breeding pea plants
- Came up w/ what we now call dominant and recessive alleles
- Dominant Alleles are expressed in an orgs phenotype
while masking the effect of another allele, if that
allele is pres
- Recessive Alleles are expressed only if homozygously
expressed.

Codominance
- When more than one allele is dominant
- Both are expressed, creating a blended or mixed trait
Ex: Blood Types
Hardy Weinberg Equilibrium
Hardy and Weinberg recognized that some alleles are in
equilibrium, meaning that they do not change.
