Which the the following are simple components of the Hardy-Weinberg model?a .Allele frequencies, variety of individuals in the populationb. Frequencies of two alleles in a gene swimming pool before and after many random matingsc. Allele frequencies in a subset that the populationd. Allele frequencies, phenotype frequencies
Which the the complying with statements is not a component of the Hardy-Weinberg principle?a. If allele frequencies in a population are provided by p and q, climate genotype frequencies will certainly be given by p2, 2pq, and also q2 for generation ~ generation.b. When alleles are transmitted according to the rules of Mendelian inheritance, their frequencies perform not readjust over time.c. Also if allele A1 is dominant to allele A2, that does not rise in frequency.d. The genotype frequencies in the offspring generation must add up to two.
