Answer:
According to question, frequency of recessive genotype(r^2)=19/100
So the frequency of recessive allele(r)=√0.19=0.43
According to Hardy-weinberg equation p+q=1
So frequency of dominant allele(q)= 1-0.43=0.57
Therefore, the frequency of dominant allele is 0.57 and frequency of recessive allele is 0.43.

For this exercise we will be re-enacting founder effect on a population of hypothetical people. You can use red and white beans (or any other small household item that comes in two colors) to complete the exercise. The beans will represent genes and the different colors will represent different alleles (gene variants). Red beans will represent the dominant (R) allele for the trait, while white beans will represent the recessive (r) allele. Humans have two copies of each gene, so...

Consider a hypothetical population with two genes. Each of these two genes have two alleles (A & a, B & b). These genes are not linked, and these genes are true dominant/recessive (i.e. not co-dominant or incomplete dominance... "A" dominant to "a" and "B" dominant to "b"). Suppose you perform a monohybrid cross of an AABB homozygote with an aabb homozygote through to the F2 generation. In 2019, the genotype frequency of individuals with "aa" (regardless of their B/b genes)...
Consider the following scenario: In a population of 1000 individuals, 490 are homozygous dominant, 420 are heterozygous, and 90 are homozygous recessive. Answer the following questions about this population. How many total alleles does this population have? How many dominant alleles does this population have? How many recessive alleles does this population have? Based on your numbers from part a, calculate the following frequencies, and give a written description of each (i.e. what does each number mean in “real world”...
1. You are studying a population of sandblossoms (Linanthus parryae) that has individuals with blue and white flowers. The allele for white flowers (A) is dominant to the allele for blue flowers (a). In the population you survey, 91 out of 100 individuals have white flowers. Based on this information: a. Calculate the frequency of the A and a alleles. b. Calculate the numbers of each genotype. 2. A population of snapdragons (Antirrhinum hispanicum) has two additive alleles for flower...
You have a cup of beans in front of you with 20 white beans and 24 red beans. These beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r). In 1997, a self-isolated group of people living on a small island was joined by a group of explorers from a nearby island. STEP 1. Create the original, self-isolated population. The self-isolated population consists of six males. Three of them are homozygous...
2.3 Problem 3 The Hardy-Weinberg equation is useful for predicting the percent of a hu- man population that may be heterozygous carriers of recessive alleles for certain genetic diseases. Phenylketonuria (PKU) is a human metabolic dis- order that results in mental retardation if it is untreated in infancy. In the United States, one out of approximately 10.000 babies is born with the disor- der. Approximately what percent of the population are heterozygous carriers of the recessive PKU allele? If you...
Question 4 O out of 1 points In a population of 1000 people, 90 have red halr, 57 have brown hair, 521 have blond hair, and 332 have black halr. In this example population, the red hair allele, r, is recess ve to alleles for black, brown, and blond hair. What is the frequency of the red hair allele in this population?
