The A and B antigens in humans may be found in water-soluble form in secretions, including saliva, of some individuals (Se/Se and Se/se) but not in others (se/se). The population thus contains “secretors” and “nonsecretors.” (a) Determine the proportion of various phenotypes (blood type and ability to secrete) in matings between individuals that are blood type AB and type O, both of whom are Se/se. (b) How will the results of such matings change if both parents are heterozygous for the gene controlling the synthesis of the H substance (Hh)?

9. The factors for normal hemoglobin (S) and sickle-cell hemoglobin (s) are considered codominants: heterozygous individuals have some normal red blood cells and some sickle cells but are not considered to have the disease. A heterozygote is said to have the sickle-cell trait but not the disease. A. What is the genotype of a man with the sickle-cell trait? B. If normal man marries a heterozygous woman, what do you expect for the genotypes and phenotypes of their children? C. If 2 heterozygous people marry and have 3 children who don’t have the disease, what is the chance that their fourth child will have the disease? D. Assume that medical science finds a treatment for sickle-cell anemia so that people with the disease can live out a normal life span but their genes are not changed. If 2 people are saved from the effects of the disease, marry, and have children, what would you expect for the genotypes and phenotypes of their children? Would the children…
1. In a particular bird species, the tips of the feathers are tinged with blue, white, or silver. The BB genotype calls for blue-tipped feathers. The WW genotype calls for white-tipped feathers. The BW genotype calls for an intermediate with silver-tipped feathers. A mating occurs between a blue-tipped bird and a white-tipped bird. What types of offspring would be expected? Give the genotypes and phenotypes of the possible offspring and the probability of each. 2. The bird species described in question 5 has an ornamental plumage on its head. The plumage feathers are either flexible or stiff. The allele for flexible plumage is dominant over the allele for stiff plumage. A male who is heterozygous for plumage and has silver-tipped wings mates with a female who has stiff plumage with silver-tipped wings. What types of offspring would be expected from this cross? Give the probability of each. 3. In some cats, the gene for tail length shows incomplete dominance. When a cat with a…
1. In cats, black coat color is dominant over gray. A female black cat whose mother is gray mates with a gray male. If this female has a litter of six kittens, what is the probability that three will be black and three will be gray?
1. In cats, white patches are caused by the dominant allele P, while pp individuals are solid-coloured. Short hair is caused by a dominant allele S, while ss cats have long hair. A long-haired cat with patches whose mother was solid-coloured and short-haired mates with a short-haired, solid-coloured cat whose mother was long-haired and solid-coloured. What kinds of kittens can arise from this mating, and in what proportions? Show your solution. Explain your answers.
1. If two raccoons with medium-sized tail bands and have the habit of washing some of their foods will be crossed, what is the probability of having F1 raccoons with: c.1 wide tail bands that won’t wash any of their food? c.2 the same genotype as the parent raccoons? 2. If a raccoon with a wide tail band that washes only some of its food is crossed with a raccoon with a narrow tail band that doesn’t wash any food, what percentage of their offspring would be medium-tailed and washes all its food? Show COMPLETE cross.
1) By convention, the recessive trait will determine the abbreviation used to track crosses if it is a mutant condition, since it stands out in contrast to the rest of the population. For example, if pea pods are typically green in color, a mutant condition might result in yellow pea pods; therefore, the lowercase letter ‘y’ would be used to depict the mutant state, yellow, while uppercase ‘Y’ would depict the wildtype (wt) condition, green. Remember that the mutant condition is not necessarily always recessive. 1 A) . If green is dominant wt (Y) and yellow is a recessive mutant condition (y), depict a Yy father mated with a YY mother in the Punnett. 1B) Considering the dominant allele, what colors are the parents in the cross above? Yy = _____________________ YY = _____________________ 1C) What colors are the offspring in the cross above? 1D) What is the phenotypic ratio of the offspring? 1E) What is the genotypic ratio of the offspring? (Remember, the genotypic ratio is based…
7. In humans, the alleles for blood type are designated I^ (A-type blood), I ^ B (B-type blood) and i (O-type blood). What are the expected frequencies of phenotypes in the following matings?

1) Imagine you discover a new mutant strain of tailless mice. Upon looking closer, you notice that I is only the females who are tailless. In paired matings with tailless females crossed with normalmales, you find that the progeny are always recovered in the following ratios: 1/3 tailless females, 1/3 normal females, 1/3 normal males. a)What is the most likely genotype of the tailless mice? b) Provide a simple explanation for the ratio: 1/3 tailless females, 1/3 normal females, 1/3 normal males.
Five human matings numbered 1–5 are shown in the following table. Included are both maternal and paternal phenotypes for ABO and MN blood-group antigen status. Each mating resulted in one of the five offspring shown to the right (a–e). Match each offspring with one correct set of parents, using each parental set only once. Is there more than one set of correct answers?
4. Marfan syndrome is a genetic trait caused by in a dominant allele. The trait causes a weakening of the aorta that can be fatal. A teenager whose mother has the syndrome (but whose maternal grandfather was not affected), and whose father was unaffected, is concerend that she may have the trait. a. What is the phenotype of each of her parents? Genotype? b. What is the chance that the teenager has Marfan syndrome?
1. A mother with blood type A has a child with blood type O, and she claims that Mister X is the father. Mister X denies that he could possibly be the father, because he has blood type B. If you were the judge presiding over this case, which of the following arguments would you find most convincing? a. Mr. X could be the father if his blood genotype is IBIB, and the mother’s blood genotype is IAIA b. Mr. X cannot be the father because a child with blood type O cannot have a parent with blood type B c. Mr. X could be the father if his blood genotype is IBi, and the mother’s blood genotype is IAi d. Mr. X cannot be the father because a parent with blood type B cannot have a child with blood type O e. Mr. X cannot be the father because the human ABO blood types are sex-linked traits 2. A monohybrid cross between two pea plants producing yellow peas, resulting in an F1 phenotypic ratio of 3:1 (three yellow pea plants to one green pea plant) indicates what about the parental pea plants?…
