What does Q represent in the Hardy-Weinberg equation?
The Hardy-Weinberg Equation
q = the frequency of the recessive allele in a population. 2pq = the frequency of the heterozygous dominant genotype. p2 = the frequency of homozygous dominant genotype.
How do you find q in Hardy Weinberg?
To find q, simply take the square root of 0.09 to get 0.3. Since p = 1 – 0.3, then p must equal 0.7. 2pq = 2 (0.7 x 0.3) = 0.42 = 42% of the population are heterozygotes (carriers).
What is P and Q biology?
In the simplest system, with two alleles of the same locus (e.g. A,a), we use the symbol p to represent the frequency of the dominant allele within the population, and q for the frequency of the recessive allele.
What does the Q represent in the Hardy-Weinberg equation quizlet?
According to the Hardy-Weinberg equation, what does ‘q’ represent? Frequency of the recessive allele.
Why is 2pq not PQ?
Note that the heterozygotes are not 2pq but pq because in each case they are only being considered for the one allele in question. If we scale all wii’s such that the largest = 1.0 we refer to these as the relative fitnesses of the genotypes. A worked example where p = . 4, q = .
Which allele is represented by the Q variable in the Hardy-Weinberg equation?
The Hardy–Weinberg principle relates allele frequencies to genotype frequencies in a randomly mating population. Imagine that you have a population with two alleles (A and B) that segregate at a single locus. The frequency of allele A is denoted by p and the frequency of allele B is denoted by q.
What is Microevolutionary change?
Microevolution is defined as changes in the frequency of a gene in a population. These are subtle changes that can occur in very short periods of time, and may not be visible to a casual observer.
Which of the following is not an example of co dominance?
D. A flower offspring of red and white flowers, which has both red and white petals. C is correct. This is not an example of codominance, because the child does not express both parents’ traits.
What is the allele frequency of Q If P 0.8 What are the genotype frequencies?
For example, if the allelic frequencies of alleles A and a in the initial population were p = 0.8 and q = 0.2, the allelic frequencies in the next generation will remain p = 0.8 and q = 0.2.
What are the frequencies of the P and Q alleles in the final population?
allele frequencies in a population will not change from generation to generation. if the allele frequencies in a population with two alleles at a locus are p and q, then the expected genotype frequencies are p2, 2pq, and q2.
