Valyrians have alleles for gene A, controlling hair color. The dominant A (silver hair) and the recessive a (brown hair). In a population of 3600 individuals, 2000 have genotype AA, 1000 have genotype Aa, and 600 have genotype aa. 1-What is the frequency of allele A? (Express the answer as a decimal with 3 places, ie .123

Valyrians have alleles for gene A, controlling hair color. The dominant A (silver hair) and the recessive a (brown hair). In a population of 3600 individuals, 2000 have genotype AA, 1000 have genotype Aa, and 600 have genotype aa. a-What is the frequency of allele a?
In a population of snails, a locus affecting shell color has 2 alleles. The D allele produces a dark shell, while the d allele produces a white shell. Heterozygote individuals (Dd) have a yellowish shell. In a sample of 150 snails, 47 snails have a white shell, and 12 have a yellow shell. What is the frequency of the D allele? Round your answer to the second decimal place (0.00)
Flower colour in snapdragon plants is a single gene trait controlled by two alleles.In a population of 350 plants, 56% of the alleles are recessive. What is the frequency of the dominant allele in the gene pool?Record your answer as a value between 0 and 1 rounded to two decimal places.
Fur colour in mice is a single gene trait controlled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between 0 and 1 rounded to two decimal places.
In corn, kernel color is governed by a dominant allele for white color (A) and by a recessive allele for yellow (a). A random sample of 152 kernels from a population that assumes Hardy- Weinberg principle reveals that 117 kernels are white. What is the frequency of individuals with the homozygous recessive genotype? Group of answer choices 0.26 0.56 0.23 0.27

A genetic mutation that causes deafness in humans has an autosomal recessive pattern of inheritance. In a study of a population of 235 Turkish children, 48 displayed the recessive phenotype. The frequency of the heterozygous genotype in the population of Turkish children described above is?
60 individuals have the genotype AA28 individuals have the genotype Aa12 individuals have the genotype aaWhat is the frequency of the A allele?Think of how many alleles in total?hint: add up the number of A alleles in this population: AA= 60+60 and Aa= 28.Add those together and divide by the total number of alleles.
Nieman-Pick Syndrome involves a defective enzyme, sphyngomylinase. It is usually fatal before the age of 3. The defective allele frequency is 0.01 in Ashkenazi populations. Let’s call the healthy allele A, and the lethal allele a. a) What is the frequency of allele A? Assuming Hardy-Weinberg equilibrium, how many people do you expect to have the three genotypes in a population of 10,000? b) AA:_______ c) Aa:________ d) aa:_________
Many genetic disorders, such as cystic fibrosis and sickle-cell disease are due to mutations in a recessive allele. You have sampled an isolated population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate: 1d. the frequency of the "AA" genotype (round to the nearest hundredth)
A population of frogs consists of 1000 individuals of which 400 are red. Red is recessive to Green. What is the frequency of the dominant allele and the recessive allele in this population? What is the frequency of individuals with homozygous dominant phenotypes? Please answer and show all work, thank you!! :)
The Rh factor is an antigen expressed on red blood cells and is controlled by a single gene. The dominant allele RH causes a person to be Rh, positive, and the recessive allele is represented as rh. Assume that a population is in Hardy-Weinberg equilibrium and 16 individuals out of 100 are Rh negative. What are the allele frequencies of RH and rh in this population? A. The allele frequency of RH is 0.80 and the allele frequency of rh is 0.20 B. The allele frequency of RH is 0.84 and the allele frequency of rh is 0.16 C. The allele frequency of RH is 0.50 and the allele frequency of rh is 0.50 D. The allele frequency of RH is 0.60 and the allele frequency of rh is 0.40
