Frequency of Dominant Allele A:
The frequency of the dominant allele A is given as 0.4. This means that out of all the alleles in the population, 40% of them are the dominant allele A.
Frequency of Recessive Allele a:
Since there are only two alleles at this gene locus, the remaining allele must be the recessive allele a. The frequency of the recessive allele can be calculated by subtracting the frequency of the dominant allele from 1.
Frequency of recessive allele a = 1 - Frequency of dominant allele A
Frequency of recessive allele a = 1 - 0.4
Frequency of recessive allele a = 0.6
Calculating the Frequencies of Different Genotypes:
To calculate the frequencies of different genotypes, we need to consider the possible combinations of alleles: homozygous dominant (AA), heterozygous (Aa), and homozygous recessive (aa).
Frequency of Homozygous Dominant (AA) individuals:
The frequency of homozygous dominant individuals can be calculated by squaring the frequency of the dominant allele A.
Frequency of homozygous dominant individuals = (Frequency of dominant allele A)^2
Frequency of homozygous dominant individuals = (0.4)^2
Frequency of homozygous dominant individuals = 0.16
Frequency of Heterozygous (Aa) individuals:
The frequency of heterozygous individuals can be calculated by multiplying the frequencies of the dominant allele A and the recessive allele a, and then doubling the result (since there are two possible combinations: Aa and aA).
Frequency of heterozygous individuals = 2 * (Frequency of dominant allele A) * (Frequency of recessive allele a)
Frequency of heterozygous individuals = 2 * 0.4 * 0.6
Frequency of heterozygous individuals = 0.48
Frequency of Homozygous Recessive (aa) individuals:
The frequency of homozygous recessive individuals can be calculated by squaring the frequency of the recessive allele a.
Frequency of homozygous recessive individuals = (Frequency of recessive allele a)^2
Frequency of homozygous recessive individuals = (0.6)^2
Frequency of homozygous recessive individuals = 0.36
Summary:
- Frequency of homozygous dominant (AA) individuals: 0.16
- Frequency of heterozygous (Aa) individuals: 0.48
- Frequency of homozygous recessive (aa) individuals: 0.36
These frequencies represent the proportions of individuals with different genotypes in the population, based on the given frequency of the dominant allele A.
The frequency of the dominant allele A is given as 0.4. This means that out of all the alleles in the population, 40% of them are the dominant allele A.
Frequency of Recessive Allele a:
Since there are only two alleles at this gene locus, the remaining allele must be the recessive allele a. The frequency of the recessive allele can be calculated by subtracting the frequency of the dominant allele from 1.
Frequency of recessive allele a = 1 - Frequency of dominant allele A
Frequency of recessive allele a = 1 - 0.4
Frequency of recessive allele a = 0.6
Calculating the Frequencies of Different Genotypes:
To calculate the frequencies of different genotypes, we need to consider the possible combinations of alleles: homozygous dominant (AA), heterozygous (Aa), and homozygous recessive (aa).
Frequency of Homozygous Dominant (AA) individuals:
The frequency of homozygous dominant individuals can be calculated by squaring the frequency of the dominant allele A.
Frequency of homozygous dominant individuals = (Frequency of dominant allele A)^2
Frequency of homozygous dominant individuals = (0.4)^2
Frequency of homozygous dominant individuals = 0.16
Frequency of Heterozygous (Aa) individuals:
The frequency of heterozygous individuals can be calculated by multiplying the frequencies of the dominant allele A and the recessive allele a, and then doubling the result (since there are two possible combinations: Aa and aA).
Frequency of heterozygous individuals = 2 * (Frequency of dominant allele A) * (Frequency of recessive allele a)
Frequency of heterozygous individuals = 2 * 0.4 * 0.6
Frequency of heterozygous individuals = 0.48
Frequency of Homozygous Recessive (aa) individuals:
The frequency of homozygous recessive individuals can be calculated by squaring the frequency of the recessive allele a.
Frequency of homozygous recessive individuals = (Frequency of recessive allele a)^2
Frequency of homozygous recessive individuals = (0.6)^2
Frequency of homozygous recessive individuals = 0.36
Summary:
- Frequency of homozygous dominant (AA) individuals: 0.16
- Frequency of heterozygous (Aa) individuals: 0.48
- Frequency of homozygous recessive (aa) individuals: 0.36
These frequencies represent the proportions of individuals with different genotypes in the population, based on the given frequency of the dominant allele A.
