frequency of the dominant allele (p) in the population

Please help with the following problem. If the frequency of the dominant phenotypes (AA + Aa) is 0.8 and the population is in Hardy-Weinberg equilibrium, can you calculate the allele frequencies? Can you calculate the genotype frequencies? Show your calculations.

See attached for the picture the questions are referencing. ln the beetles described in the animation, there were two alleles for color, brown and green. Suppose that you discover a very small population of these beetles, consisting of the individuals shown below. How can you calculate the frequency of each allele in ihis

4. In the Yucca plant, flower color is determined by a system of incomplete dominance. The genotype BB gives blue flowers, Bb gives lilac flowers, and bb gives white flowers. In a population of yucca plants, 8 had blue flowers, 84 had lilac flowers, and 52 had white flowers. a. What is the frequency of the B allele in this

3. In plants, flower color is controlled by incomplete dominance, where red and blue are the two homozygous conditions and purple indicates heterozygous. An initial population contains 14 red, 70 purple, and 24 blue individuals. Give exact allele and expected genotype frequencies for this population. Now assume that the heter

1. In ladybugs, wings with 4 spots are recessive to those with 2. Assume 11% of the ladybugs have 4 spot wings. If the mutation rate of 2 spot to 4 spot alleles is 0.047, what percentage of the next generation will be heterozygous? 2. You look at two populations of moose, one from Canada, and one from Newfoundland, an islan

I need to understand the answer to the following multiple choice question. Which of the following causes changes in allele frequencies? a. genetic drift b. mutation c. natural selection d. gene flow from migration e. all of these

A) Address the following Hardy-Weinberg Equilibrium problem. i) A population of iguanas on the Galapagos Islands has 20 individuals with webbed feet and 180 individuals with the dominant trait of non-webbed feet. What are the frequencies of webbed feet and non-webbed feet traits in this population? ii) H

1. Imagine a population of 10,000 humans living on an isolated island. Every generation, an average of one individual is born with cystic fibrosis, a fatal genetic disease caused by a recessive allele (ie., individuals with the condition are cc, Cc individuals are unaffected, but carry the allele) What are the frequencies o

Using the Hardy Weinberg equilibrium, calculate the frequencies of this situation: 500 individuals have 80 green flowered plants; the remaining plants have blue flowers. You know that flower colour is determined by one gene with two alleles. Looking at your population, can you determine which allele is dominant? Calculat
