A population has 25 individuals of genotype AA, 25 individuals of genotype aa, and 50 individuals of genotype Aa.  Is this population in Hardy Weinberg equilibrium?  Why or why not?

In a population of 1000 individuals, 415 are AA, 395 are Aa, and 190 are aa. Assume any difference in expected versus observed genotype frequencies greater than 3% is statistically significant. Is this population in Hardy-Weinberg equilibrium? 1.yes 2.no 3.more info needed

In pea plants, the color purple is dominant to the color white. A farmer with an isolated patch of pea plants counts 36 purple-flowering plants and 64 white-flowering plants. Assuming the patch is in Hardy-Weinberg equilibrium, what is the frequency of the white allele? 0.75 0.64 0.80 0.36

Assuming a population is in Hardy-Weinberg equilibrium, an increase in the frequency of the p(A) allele from 0.6 to 0.9 would result in which of the following outcomes?   a. A decrease in the number of homozygous dominant individuals within the population   b. A decrease in the number of homozygous recessive individuals within the population   c. An increase in the number of homozygous recessive individuals within the population   d. An increase in the number of heterozygotes within the population   e. No change in genotypic frequency within the population
