Best answer: What does p2 in the below mentioned Hardy Weinberg equation indicate?

Contents

To determine the genotype breakdown we use the equation p2 + 2pq + q2, where p2 represents homozygous dominant genotype, 2pq represents heterozygous genotype, and q2 represents homozygous recessive genotype.

What does p2 represent within the Hardy-Weinberg equation?

In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa. In addition, the sum of the allele frequencies for all the alleles at the locus must be 1, so p + q = 1.

What does P equal in Hardy-Weinberg?

The Hardy-Weinberg Law is an equation for calculating the frequencies of different alleles and genotypes in a population in genetic equilibrium and expressed by the formula p + q = 1 where p is the frequency of the dominant allele and q is the frequency of the recessive allele.

What was the purpose of Hardy and Weinberg’s work?

Hardy Weinberg’s work shows that the percentage of alleles in genepool will remain in equilibrium when there is no new mutation and evolutionary forces are not working.

What does the Hardy Weinberg principle predict?

The Hardy–Weinberg principle provides a mathematical model, which predicts that allele frequencies will not change from generation to generation. … where is the frequency of one (usually the dominant) allele and is the frequency of the other (usually recessive) allele of the gene.

How do you find P 2 in Hardy-Weinberg?

Since p = 1 – q then 1 – 0.59 = 0.41. Now that we know the frequency of each allele, we can calculate the frequency of the remaining genotypes in the population (AA and Aa individuals). AA = p2 = 0.41 x 0.41 = 0.17; Aa = 2pq = 2 (0.59) (0.41) = 0.48; and as before aa = q2 = 0.59 x 0.59 = 0.35.

Is PP genotype or phenotype?

There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).

How do you find the P and Q values in Hardy-Weinberg?

The Hardy-Weinberg equation used to determine genotype frequencies is: p2 + 2pq + q2 = 1. Where ‘p2‘ represents the frequency of the homozygous dominant genotype (AA), ‘2pq’ the frequency of the heterozygous genotype (Aa) and ‘q2‘ the frequency of the homozygous recessive genotype (aa).

What does the Hardy-Weinberg law of equilibrium assume Anthro quizlet?

Hardy-Weinberg equilibrium assumes: no gene flow, mutation, genetic drift, or natural selection. “Fitness,” in an evolutionary sense, refers to an individual’s: reproductive success.

What is the Hardy-Weinberg equation to represent allele frequency in gene pool?

Everyone produces the same number of offspring. Hardy-Weinberg principle can be illustrated mathematically with the equation: p2+2pq+q2 = 1, where ‘p’ and ‘q’ represent the frequencies of alleles. P added to q always equals one (100%).

IT IS SURPRISING:  What does it mean that alleles segregate?

What does the Hardy-Weinberg principle predict 3 marks?

The Hardy-Weinberg principle is a theorem that applies to diploid organisms that are sexually reproducing. It predicts that: The allele frequencies in a population will not change from generation to generation.

What does the Hardy-Weinberg principle predict about the frequency of the T allele?

(ii) What does the Hardy-Weinberg principle predict about the frequency of the t allele after another 10 generations? (b) Several years later, scientists repeated their study on this population. They found that the frequency of the recessive allele had decreased.
