In the Ireland, 10% of the population is red
haired. Assuming mating is random, what is the frequency of
heterozygotes in Ireland?
It is given that 10% of the individual in a population have red hair. The frequency of red hair individual is 0.10
The allelic frequency for red (r) allele is √0.10= 0.316227766
The allelic frequency of R is 1- r= 1-0.31622776=-l 0.683772234
The heterozygous frequency is 2× R×r = 2×0.316227766× 0.683772234= 0.432455532
On round off upt9 two decimal place, the answer is 0.43

In a hypothetical population which is in Hardy Weinberg equilibrium, the frequency for a recessive allele is 30%. What percentage of the population would be expected to show the dominant trait in the next generation? Humans who are born homozygous for the recessive sickle cell allele die of sickle cell anemia, while those who are heterozygous are resistant to malaria (see chapter 4 for more information on this balanced polymorphism). 4% of the population of the Congo are homozygous recessive for...
In a population of flowers, red is dominant to white. Assuming the population is in HWE, if the red allele frequency is 0.46, what is the red phenotype frequency? answer to two decimals
in a study, 8 long-haired rats and 7 short haired rats were selected at random the heights of these rats were then measured. let μ1 and μ2 be the population mean height of both the long-haired and short-haired rats (respectively). Assume that the length measurements for both populations are normally distributed. long-haired rats: n1=8, x̄1=185, s1=8 short-haired rats: n1=7, x̄2=198, s2=10 i) what is the evidence (very strong / strong / moderate / little or no) we have against the...
In an infinitely large, diploid, random-mating population, we observe the frequency of nonsense mutations is equal to 10^-4 in a gene. A) If we assume the nonsense mutations cause complete infertility and are completely dominant, what is the nonsense mutation rate per gene per generation? (2 points) B) If we assume the nonsense mutations cause complete infertility but are complete recessive, what is the nonsense mutation rate? (2 points)

A) If we assume the nonsense mutations cause complete infertility and are completely dominant, what is the nonsense mutation rate per gene per generation? (2 points) B) If we assume the nonsense mutations cause complete infertility but are complete recessive, what is the nonsense mutation rate? (2 points)
A population of birds has 24 animals with red tail feathers and 52 animals with blue tail feathers. Blue feathers are the dominant trait. a. What is the frequency of the red allele? b. What is the frequency of the blue allele? c. What is the frequency of the heterozygotes? d. What is the frequency of birds homozygous for the blue allele? e. What is the frequency of birds homozygous for the red allele?
2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...
What is the probability that a lady has a red-haired gene? The probability of her mother having the gene is 2/3 and the probability of her father having the gene is 1/4.
QUESTION 48 What would be the long-term outcome in this population (AA: 400, red dermis: Aa: 400, red dermis:aa: 400, blue dermis) if complete assortative mating continues? Fixation of the A allele CLoss of the A allele Stabilization of allele frequencies in the population Loss of all the heterozygotes Population will stay at the current, balanced distribution of genotypes 2 points The diagram below represents an alignment of a randomly cut portion for alcohol dehydrogenase (ALDH), a conserved homologous gene,...
A randomly mating population of dairy cattle contains an autosomal-recessive allele causing dwarfism. If the frequency of dwarf calves is 10%, what is the frequency of heterozygous carriers of the allele in the entire herd?
