There are 24 people. 9 have green eyes, 4 have brown eyes, 5 have hazel eyes, and 6 have blue eyes. 3 people are then selected at random without replacement.

There are 24 people. 9 have black hair, 4 have brown hair, 5 have blonde hair, and 6 have red hair. 3 people are then selected at random without replacement. Solve the following probabilities: (a) What is the probability that all 3 people selected have red hair. (b) What is the probability that 2 people selected have the same color hair color, and the other person selected has a different hair color

4. In a given population, 16% of the population has blue eyes and 84% has brown eyes. Although eye color is a polygenic trait, let us assume for this problem that the brown-eyed allele is dominant to the blue-eyed allele and that the population is in Hardy-Weinberg equilibrium. What are the gene frequencies for brown eyed and blue-eyed alleles? = '16 Pa Brown-eyed allele frequency: _ qe 0.4 Pa 0.4 Blue-eyed allele frequency: - In this same population, there are...

Uption 4. The inheritance of hair and eye color is very complicated. Scientists have found approximately 10-20 genes responsible for determining hair and eye color in humans (sheesh - I thought a dihybrid cross with 2 genes was bad...). Although many genes are involved in producing these phenotypes, it does seem that just a few genes play a major role in determining the color of our hair and eyes. The following is a simplified, but still somewhat realistic view of...

An urn contains 6 red, 9 green, and 11 blue balls. The following is repeated 3 times: a ball is selected from the urn at random and removed (called “sampling without replacement”). Give your answers to 3 significant digits. (a) What is the probability that all 3 selected balls are the same color? (b) What is the probability that all 3 selected balls are different colors? (c) Repeat part (a) assuming “sampling with replacement”. That is, the following is repeated...

Wild horses can have short or long manes and brown or green eyes. Mane phenotype is controlled by a single gene with two alleles, M (long mane) and m (short mane), where M is dominant to m. The eye phenotype is also controlled by a single gene with two alleles, B (brown eyes) and b (green eyes), where B is dominant to b. The mane and eye phenotype genes assort independently. a. In the cross MmBb x mmBb, what is...

In a region, 80% of the population have brown eyes. If 15 people are randomly selected, find the probability that at least 13 of them have brown eyes. Is it unusual to randomly select 15 people and find that at least 13 of them have brown eyes? Why or why not? The probability that at least 13 of the 15 people selected have brown eyes is (Round to three decimal places as needed.)

Assortative mating: Assortative mating is a nonrandom mating pattern where individuals with similar genotypes and/or phenotypes mate with one another more frequently than what would be expected under a random mating pattern. Researchers studying this topic collected data on eye colors of 205 Scandinavian men and their female partners. The table below summarizes the results (rows represent male eye color while columns represent female eye color). For simplicity, we only include heterosexual relationships in this exercise. (please round any numerical...
