# Hardy-Weinburg Equlibrium?

##
If a population that is in Hardy-Weinburg equilibrium has 500 individuals, with allele frequencies for p and q of 0.55 and 0.45, respectively, and 30% of the heterozygotes are killed by a natural disaster, how many heterozygotes are left? Will the population stay in genetic equilibrium?

##### 1 Answer

#### Answer:

Heterozygotes left:

Genetic Equilibrium: No

#### Explanation:

Population:

#p = 0.55# #q = 0.45#

To find the heterozygotes of the individual, you have to multiply.

Now,

Heterozygotes left:

*or* the rounded answer...

For genetic equilibrium to occur p and q must equal each other without any factors of mutation, random mating, migration, *genetic drift*, or for a species to have an infinitely large population.

For this problem, since some of the species died off; **No, this species will not stay in genetic equilibrium.**
