If a new allele appears in a population, the Hardy-Weinberg formula cannot be used. This is because there is now no equilibrium.
R represents the dominant round allele, and rrepresents the recessive wrinkled allele. :D
There is no possibility that a male will inherit and X-linked recessive allele from his father because for a male child the father only contributes the Y chromosome to his son (of the XY pair he has). If the fater's X chromosome has a recessive allele then it is 100% certain that he will pas this on to all his daughters.
Non-random mating refers to a situation in which individuals in a population choose mates based on specific traits or characteristics rather than randomly. This can lead to assortative mating, where individuals mate with similar phenotypes, or disassortative mating, where they choose partners with different traits. Non-random mating can influence genetic diversity and evolutionary dynamics within a population. It often results in changes in allele frequencies over time, impacting the population's overall genetic structure.
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.

Based on the Hardy-Weinberg Principle the rate at which a particular allele occurs in a population is its frequency.
Based on the Hardy-Weinberg Principle the rate at which a particular allele occurs in a population is its frequency.
In the Hardy-Weinberg equation, q2 represents the frequency of homozygous recessive individuals in a population for a specific allele. It is calculated by squaring the frequency (q) of the recessive allele in the population.
To solve Hardy-Weinberg problems effectively, you need to understand the formula and assumptions of the Hardy-Weinberg equilibrium. Calculate allele frequencies, use the formula to find genotype frequencies, and compare them to the expected frequencies. Repeat for each allele and genotype.
The population is evolving.
A population in which the allele frequencies do not change from one generation to the next is said to be in equilibrium.
To effectively solve Hardy-Weinberg problems, one must understand the formula and assumptions of the Hardy-Weinberg equilibrium. This formula is used to predict the frequency of alleles in a population over generations. By plugging in the given information, such as allele frequencies or genotype frequencies, one can calculate the expected frequencies of genotypes in the population. It is important to remember the assumptions of the Hardy-Weinberg equilibrium, such as a large population size, random mating, no migration, no mutation, and no natural selection. By applying the formula and understanding these assumptions, one can effectively solve Hardy-Weinberg problems.
To solve a Hardy-Weinberg problem, you need to use the formula p2 2pq q2 1, where p and q represent the frequencies of two alleles in a population. First, determine the allele frequencies using the given information. Then, use the formula to calculate the expected genotype frequencies. Compare the expected and observed genotype frequencies to determine if the population is in Hardy-Weinberg equilibrium.
To work out Hardy-Weinberg problems, you need to first identify the frequencies of the alleles in a population. Then, you can use the Hardy-Weinberg equation (p^2 + 2pq + q^2 = 1) to calculate the frequencies of genotypes and phenotypes in the population. Remember that p represents the frequency of one allele and q represents the frequency of the other allele in the population.
Using Hardy-Weinberg equilibrium, the frequency of heterozygotes (Aa) is calculated as 2 * p * q, where p is the frequency of allele A and q is the frequency of allele a. Given q = 0.1, p = 0.9, so the frequency of heterozygotes is 2 * 0.9 * 0.1 = 0.18. Therefore, 18% of the population is heterozygous for this allele.
