Answer :
Genotype frequency of red hair (q2) = 90 / 1000
= 0.09
The frequency of red hair allele (q) = √0.09
= 0.3 (answer).
Add Answer to:
Question 4 O out of 1 points In a population of 1000 people, 90 have red...

Suppose there is a small population of birds that have either brown chest feathers or yellow chest feathers, and the Question Not yet answered allele for the brown feathers is dominant. The frequencies for the two alleles in the population are approximately equal Points out of 1.00 For each event or condition described below, answer the following questions. P Flag question o What mechanism? Identify whether the event is natural selection, genetic drift, or...

The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...

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...

5. Fur colour in mice is a single gene trait controled 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 O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...

I need help with questions 1 through 2, thank you!
The Esatina salamanders (Ensatina eschscholtzii), shown above, live along the West Coast of North America from Vancouver to Baja California. We will be focusing two populations: 1. individuals that live in Northern California and represent a more ancestral population 2. individuals that live in Southern California. Researchers have found that these all individuals of this salamander species have two color phenotype, either red or blotchy. Genetic analysis has shown that...
