Homework Answers
a]
List of possible outcomes are:
blond/blond , blond/brown , brown/blond and brown/brown
b]
The probability that a child of these parents will have the browm/brown genotype is = ratio of favourable outcomes to the total number of outcomes = 1 / 4 = 0.25
c]
Probabilty that the child will have blond hair color = 3 / 4 = 0.75

Among 450 randomly selected drivers in the 20-24 age bracket, 9 were in a car crash in the last year. If a driver in that age bracket is randomly selected, what is the approximate probability that he or she will be in a car crash during the next year? Is it unlikely for a driver in that age bracket to be involved in a car crash during a year? Is the resulting value high enough to be of concern to...

LOUISE Homework Quizzes & Tests A gene is composed of two alleles. An allele can be either dominant or recessive. Suppose that a rusband di wile, allele but do not have the disease, decide to have a child. Because both parents are carriers of the disease, each has one dominant normal-cell allele (S) and one recessive sickle-cell allele (s). Therefore, the genotype of each parent is Ss. Each parent contributes one allele to his or her offspring with each allele...

Background for Discussion: Blood type is determined by the "alleles" that are inherited from the parents Alleles are possible types of a particular gene, in this case the blood type gene. There are four main blood types A, B, AB, or O; and three basic type alleles A, B, and O. Children have two alleles, one inherited from each parent. Blood types A and B are called co-dominant alleles, while type O represents the absence of a factor and is...

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...

Assume that tail length in mice is a quantitative trait involving two genes, each with 2 alleles. One allele at each gene contributes to long tails, the other allele at each gene does not (small tails). The genes are located on different autosomes. Mice with 0 contributing alleles have tails that are 4 cm in length; mice with tails with 4 contributing alleles are 12 cm in length. Determine the phenotypic ratio from an F2 from a true breeding parent...
In gerbils, the gene that specifies coat color is sex‑linked and has multiple alleles, as follows:...
In gerbils, the gene that specifies coat color is sex‑linked and has multiple alleles, as follows: B ‑ black, br ‑ brown, by ‑ yellow, and b ‑ albino. The allele br is incompletely dominant over by, the combination br by giving tan color; otherwise, dominance is in the order given ‑‑ B, br, by, b. (For your information, gerbils are mammals.) A black gerbil mated with a yellow gerbil gave one brown male and one black female offspring. a....
