5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...

A researcher decides to examine the effects of a new drug on the activity level of animals. Three samples of rats are selected with n=5 in each sample. One group gets no drug, one group gets a small dose, and a third group gets a large dose. The researcher records the activity level for each animal. The data from this experiment are presented below. No drug Small dose Large dose 5 5 10 3 5 12 1 9 9 1...

Hello, I just need someone to check my answer: The answer I choose are in bold points. 1. What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants? Recessive genes occur more frequently in the F1 generation than do dominant ones Traits are inherited in discrete units, and are not the results of "blending" There is considerable genetic variation in garden peas Genes are composed of DNA 2. In a particular plant, two genes...
