- In cats, the allele (B) produces black color but (b) producesyellow color. These alleles are co‐dominant to each other. Aheterozygote produces a tortoise‐shell color. The alleles (B)and (b) are sex‐linked as well. Cross a tortoise‐shell femalewith a yellow male. What percent of their offspring will be yellow? What percent of their offspring will be black? What percent of their offspring will be tortoise shell?Plsssssssss helppppppppp, how can NF1 be spontaneous? Include the following terms: -genotype - phenotype - homozygous - heterozygous - inheritance - alleles - dominant - recessiveTwo mothers give birth to sons at the same time at a busy urbanhospital. The son of mother 1 has hemophilia, a disease causedby an X-linked recessive allele. Neither parent has the disease.Mother 2 has a son without hemophilia, despite the fact thatthe father has hemophilia. Several years later, couple 1 suesthe hospital, claiming that these two newborns were swappedin the nursery following their birth. As a genetic counselor, youare called to testify. What information can you provide the juryconcerning the allegation?
- 3. Codominance is when two dominant alleles of contrastingpair fully expressed at the same time in heterozygousindividual. Which of the following situation is an example ofcodominance?A. Jo mated the red bull with the white cow to produce a roan cow.B. Melissa traces her blood type by crossing the blood type of herparents.C. James passed a genetic disorder hypertrichosis pinnae aurisor hairy ear to his son.D. Tess crosses the red carnation flower plant with white flowercarnation plant to produce a pink flower plant.Sesame plants produce seed pods with one chamber (O) or three chambers (o), and leaves that are normal (N) or wrinkled (n). The two traits are inherited independently. Determine the genotypes and phenotypes of the two parents that produced the following offspring: 304 with one-chamber pods and normal leaves; 100 one-chamber pods and wrinkled seeds; 298 with three-chamber pods and normal leaves; 103 with three chamber pods and wrinkled leaves.Plsssssss helppppppp, should an individual have have children if they know there is a chance they could pass on a trait that could have negative health consequences? Should individuals screen their genes through their health care provider before deciding to have children?
- If a white female mouse without spots is crossed to a gray male with brown spots, what proportion of their daughters would have the same phenotype as their mother? W = long whiskers (dominant) W'= black fur (incomplete dominance) w = short whiskers (recessive) W = white fur (incomplete dominance) E = long ears (dominant) e = short ears (recessive) S = presence of brown spots (dominant and sex-linked) s = absence of brown spots (recessive and sex-linked) The answer is none but i don't get how to set up the punnett square.4.) A man and a woman have a child. The father is blood type A, and one of his parents was blood type A and the other was blood type O. The mother is blood type B, and one of her parents was blood type B, the other type O. Both the father and the mother are carriers of the Bombay allele. (Neither of the type-O grandparents were type O because of the Bombay allele – they had the regular type O genotype.) WhataretheoddsthattheirbabywillhavebloodtypeO?

- A red flower(WW) and white flower(ww) (P1) have the ability to create pink flowers in thier offsprings (F1). What type of phenotype is shown and what would be the phenotypic (%) of pink flowers for the following? (WwxWw) I know if is an incomplete dominance at 50 percent. But i am having a problem with the Punnett SquareWe will examine some human phenotypes that are controlled by a single gene. For each characteristic, you will determine your phenotype, possible genotype(s), and the frequency of your phenotype in the class. Tongue-rolling: a single gene with two alleles, R and r, determines a person’s ability to roll their tongue into a U shape. A person that cannot roll their tongue is homozygous recessive (rr). What is your phenotype? _____ What is your genotype(s)? _____ What is the frequency of your phenotype? (show your work) _________ Widow’s peak: a single gene with two alleles, W and w. The dominant allele (W) results in a hairline that forms a distinct point in the center of the forehead. What is your phenotype? _____ What is your genotype(s)? ____ What is the frequency of your phenotype? (show your work)Labrador retrievers may be black, brown, or golden in color (seethe chapter opening photograph on p. 53). Although each colormay breed true, many different outcomes occur if numerous littersare examined from a variety of matings, where the parentsare not necessarily true-breeding. The following results showsome of the possibilities. Propose a mode of inheritance that isconsistent with these data, and indicate the corresponding genotypesof the parents in each mating. Indicate as well the genotypesof dogs that breed true for each color.(a) black * brown ¡ all black(b) black * brown ¡ 1/2 black1/2 brown(c) black * brown ¡ 3/4 black1/4 golden(d) black * golden ¡ all black(e) black * golden ¡ 4/8 golden3/8 black1/8 brown(f) black * golden ¡ 2/4 golden1/4 black1/4 brown(g) brown * brown ¡ 3/4 brown1/4 golden(h) black * black ¡ 9/16 black4/16 golden3/16 brown
