# Quick Answer: What must the frequency of the recessive allele be?

Contents

## What is the frequency of the recessive allele Hardy-Weinberg?

In Hardy-Weinberg terms, this means q squared is 0.01 and q (the frequency of the recessive allele) is 0.1. Since p + q = 1, then p, the frequency of the dominant allele, must be 0.9.

## What does an allele frequency of 0.5 mean?

For instance, if all the alleles in a population of pea plants were purple alleles, W, the allele frequency of W would be 100%, or 1.0. … However, if half the alleles were W and half were w, each allele would have an allele frequency of 50%, or 0.5.

## What is the frequency of the recessive allele quizlet?

Therefore, the frequency of the dominant phenotype equals the sum of the frequencies of AA and Aa, and the recessive phenotype is simply the frequency of aa. Therefore, the dominant frequency is 64% and, in the first part of this question above, you have already shown that the recessive frequency is 36%.

## How do you find the frequency of an allele?

An allele frequency is calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population. Allele frequencies can be represented as a decimal, a percentage, or a fraction.

## What is the Hardy-Weinberg symbol for the frequency of the dominant allele?

² is the frequency of individuals with the homozygous dominant genotype.

## When an allele reaches a frequency of 1 in a population we say that it has become?

When an allele reaches a frequency of 1.0 (or 100%), we say that it has become “fixed” in the population’s gene pool (i.e., the only allele present). When an allele reaches a frequency of 0.0 (or 0%), we say that it has been “lost” from the population’s gene pool.

## What does a low FST value mean?

The low FST value for the relationship between population A and B means that they show high levels of breeding and the high FST value for population C and population A or B means that they show low levels of breeding with one another.

## Which of the below are conditions that must be met for a population to exist in Hardy-Weinberg equilibrium?

The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, (4) Random mating, and (5) No natural selection.
