In horses, tobiano is a white spotting pattern. The tobiano allele (T) is dominant over the non-tobiano (t) allele. In an ideal horse population exhibiting Hardy–Weinberg equilibrium, 350 horses out of 465 are non-tobiano.    a. Calculate the number of homozygous dominant tobiano horses.   Answer b. Calculate the number of heterozygous horses.                               Answer c. Calculate the number of tobiano horses in the population.

the aggresive behavior in cats is controlled by a completely dominant gene locus A. There are 46 docile cats in subdivision with a population of 158. Question: Determine if how many animals are heterozygous and how many animals have the dominant allele? provide solution

In a population of 500 fruit flies, 250 are genotype RR, 100 are genotype Rr and 150 are genotype rr. Determine the allele frequencies for this gene in this population. Remember that the frequencies should add to 1. Please show your work.

A genotype of aabbDDEeGg mates with aaBbDdEeGG. What is the probability that a child will result from the matings with the genotype AAbbDdEeGG? Group of answer choices 6.25 % 25 % 3.125 % 1.5625% 0 %

If one parent is dominant tall, and one parent is mixed hybrid, what is the phenotype in percentage (%) for the possible offspring? Use the reference sheet below to answer.

We observe disruptive selection when the extreme values of a trait such as light and dark coat colors are selected for instead of a medium coat color? A. true  b. False

Albinism is due to a recessive allele of an autosomal gene. Let a represent the albino allele and A represent the normal non-albino allele. If one out of every 10,000 people were albino and assuming that the population is in Hardy-Weinberg equilibrium, A. what would be the phenotype frequencies of albino and non-albino ? B. what would be the allele frequencies of a and of A? C. what fraction of people can be expected to be of the genotype Aa? D. what fraction of people can be expected to be of the genotype AA?

A mountain region has a population of 5,000 mountain goats. You score these animals for the R locus and find that this locus has two alleles, R (dominant) and r (recessive). 3200 individuals are homozygous dominant, 1,600 are heterozygous, and 200 are homozygous recessive.  a) Calculate the allele frequencies for this population. Show your work.       b) Calculate the observed genotypic frequencies for this population. Show your work.         c) Calculate the expected genotype frequencies if the population is in Hardy-Weinberg equilibrium. Show your work.         d) Does this population appear to be at H-W equilibrium? Why or why not? (You do not need to analyze this statistically).

Suppose a population of mice is subject to a few years of very cold, dry winters that drastically decreases their numbers. After the decrease in population size, there was a population of 200 mice, with 182 showing the dominant long tail phenotype and 18 showing the recessive short tail phenotype. a. What is the frequency of the recessive allele? b. What is the frequency of the dominant allele?

For a 2 allele locus, p=0.7.  If the population consists of 100 individuals, how many are homozygous for the q allele?
