(16) What are the 5 main assumptions of the Hardy-Weinberg Equilibrium? Be able to use the equation to determine if evolution has occurred for a trait (BRING A CALCULATOR).

A. 5 main assumptions are – mating is random; mutations do not occur; the population is large, so that genetic drift is not a significant factor; there is no migration; and natural selection does not occur.

B.1. infinite population size (there are infinitely many individuals in the population)
2. there is no movement of individuals from population to population
3. there is no mutation (no biochemical changes in DNA that produce new alleles.)
4. there is random mating (this means that with regard to the trait we're looking at, individuals mate at random -- they don't select mates based on this trait in any way.)
5. the different genotypes (for the genetic trait we're studying) have equal fitness. This means there is no natural selection affecting this trait (remember one of the conditions for natural selection is that some traits result in higher fitness than others.)

C.There are five main assumptions of the Hardy Weinberg equation.
Infinite population size
No movement of individuals among population.(genetic drift)
There is no mutation.
Random mating
Different genotypes
No natural selection
A = #A/#total
a = #a/#total

Hardy-Weinberg Equilibrium is defined as the situation in which no evolution is occurring.
A trait (coded for by some gene with alternate alleles) in a population will be in Hardy-Weinberg Equilibrium if five assumptions are met. These are:
1. infinite population size (there are infinitely many individuals in the population)
2. there is no movement of individuals from population to population
3. there is no mutation (no biochemical changes in DNA that produce new alleles.)
4. there is random mating (this means that with regard to the trait we're looking at, individuals mate at random -- they don't select mates based on this trait in any way.)
5. the different genotypes (for the genetic trait we're studying) have equal fitness. This means there is no natural selection affecting this trait (remember one of the conditions for natural selection is that some traits result in higher fitness than others.)

E.1. mating is random
2. mutations do not occur
3. the population is large
4. there is no migration
5. natural selection does not occur
