Which term in the Hardy Weinberg equation predict the frequency of homozygous recessive?

From the number of homozygous recessive organisms (represented by q2 ) in a population, allele frequency ( q ) of recessive allele is determined. Hence 1-q is allele frequency (p) of dominant allele.

What is the frequency of homozygous recessive?

The frequency of the recessive allele. Answer: Since we believe that the homozygous recessive for this gene (q2) represents 4% (i.e. = 0.04), the square root (q) is 0.2 (20%). The frequency of the dominant allele. Answer: Since q = 0.2, and p + q = 1, then p = 0.8 (80%).

What is the frequency of the homozygous dominant genotype according to the Hardy Weinberg equation?

According to the Hardy-Weinberg principle, the square root of the homozygous genotype frequency is equal to the allele frequency. The dominant allele frequency is 0.7.

What does Hardy Weinberg equation predict?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. If the p and q allele frequencies are known, then the frequencies of the three genotypes may be calculated using the Hardy-Weinberg equation. …

What is the frequency of homozygous dominant individuals?

The frequency of homozygous dominant plants (p2) is (0.6)2 = 0.36. Out of 100 individuals, there are 36 homozygous dominant (YY) plants. The frequency of heterozygous plants (2pq) is 2(0.6)(0.4) = 0.48. Therefore, 48 out of 100 plants are heterozygous yellow (Yy).

What will happen to the frequency of the recessive allele?

The answer is the frequency of the recessive allele will increase.

What is an example of allele frequency?

Example: assuming that in a human population, there are 100 individuals. Since each of them would have two alleles for a particular character (one allele inherited from the father, the other allele from the mother), the total number of genes in this population is 200 (=100 x 2). … Variant: allelic frequency.

How do you find the frequency of homozygous dominant?

Use the Hardy-Weinberg equilibrium.

  1. Alleles: p+q=1.
  2. p=frequency of the dominant allele. …
  3. p2=frequency of homozygous dominant genotype. …
  4. In your scenario, the dominant phenotype has a frequency of 0.19 .
  5. This is misleading, since both the p2 and 2pq terms represent the dominant phenotype. …
  6. If q2=0.81 , we can determine q .

How do you calculate phenotype frequency?

Allele Frequency

  1. Allele frequency is most commonly calculated using the Hardy-Weinberg equation, which describes the relationship between two alleles within a population. …
  2. To find the number of alleles in a given population, you must look at all the phenotypes present. …
  3. 1 = p2 + 2pq + q2

What is the phenotype frequency?

Relative phenotype frequency is the number of individuals in a population that have a specific observable trait or phenotype. … Relative genotype frequency and relative allele frequency are the most important measures of genetic variation.
