Summary
These notes explain the concept of Hardy-Weinberg equilibrium, which describes a theoretical population where allele and genotype frequencies do not change over generations. Five conditions must be met for this equilibrium to happen – no mutations, no gene flow, random mating, a large population size, and no natural selection. The notes also highlight how to calculate allele and genotype frequencies.

# Hardy-Weinburg Equalibrium Is A state of a population when the commonality of alleles in a population the genotype in that population will stay the same over generations. Versions of genes Evolution is the change in frequency alleles population in Hardy W. equalibrium are Not evolving. Can mathamatically calculate H.W.E by frequency level * **P** = freq(A) * **q** = freq(a) **HWE** $P^2 + 2pq + q^2 = 1$ (%) **5 NEEDS for HWE** - No mutation - genes not affected - duplicated or deleted - **Random mating** - organism mate randomly -no preference to genotype - **No gene flow** - neither Individuals or Sperm/egg enter or exit population - no one leaves no one enters - **Very large population** - no change for cross breeding - **No Natural Selection**
