In a population, the dominant phenotype of a certain trait occurs 91% of the time. What is the frequency of the dominant allele?

The agouti gene determines coat colour in mice. Heterozygous mice have yellow coats, while homozygous dominant mice have black coats. However, having two copies of the recessive alleles is lethal. In a population of 2 000 mice, 1 082 mice have black coats. a) Calculate the frequency of each allele. Show all your work and express your answer as a value between 0 and 1 rounded to two decimal places.  b) What percentage of the mouse population is expected to be carriers of the lethal allele? Show all your work and express your answer rounded to one decimal place.  c) How many mice will die during fetal development? Show all your work and round your answer to the closest whole number.

A given autosomal locus has three possible alleles (A1, A2, and A3). Assuming that the numbers of individuals with the six possible genotypes are as follows, what would be the frequency of the A1 allele in the population?   A1A1 = 30 A1A2  = 27 A2A2 = 12 A1A3 = 17 A2A3   = 10 A3A3 = 4 What would be the frequency of the A3A3 genotype? Assume the population is under Hardy-Weinberg equilibrium.   A. 0.182   B. 0.27   C. 0.03   D. 0.317   E. 0.107   F. 0.09

This lab exercise requires that we count certain Mendelian traits among students present in the lab. Your professor will explain each trait being addressed and will then ask students to identify if they are dominant or recessive for that specific trait. The collected traits will then be plugged into the Hardy-Weinberg Equilibrium formula in order to calculate frequency of Homozygous dominant, Heterozygous and Homozygous recessive individuals in the same. p2 + 2pq + q2 = 100 given data: trait: hair swirl 19 individuals total. 10 had the homozygous dominant hair swirl trait: clockwise the nine other were recessive please do a step by step explanation with the calculation using this data, as I am very unfamiliar with what values mean what and the equation itself thank you!
