2. Cows have codominance inheritance rules for their coat color. Cows with the genotype BB are completely black, those with the genotype WW are completely white, and with genotype BW have black and white spots across their body. Draw a Punnett Square that shows the genotypes and phenotypes of the offspring from a heterozygous coated cow and a homozygous white coated cow? Indicate also the genotypic and phenotypic % below: Genotypic %: Phenotypic %:

3. In cats, agouti coat (uneven colored fur) is dominant to a solid coat. Brown coat color is dominant to chocolate color coat. Solid brown fur Agouti fur Solid fur Chocolate colored fur pattern pattern An agouti cat http://www.eurocatfancy.de/en1/nav/cat-genetics/dominance_of_genes.html Cross a cat that is heterozygous agouti and chocolate colored with a cat with a solid coat and is heterozygous brown. a. What percentage of the offspring is agouti and brown? b. What percentage of the offspring is solid and chocolate?
2. Brown eyes are dominant over blue eyes in humans. Having a peaked hairline is dominant over having a smooth hairline in humans. Two such humans decide to have offspring – who will also be human, because you know – genes. One of the parents has blue eyes and is heterozygous for a peaked hairline. The other parent is brown-eyed with a peaked hairline but is heterozygous for both traits. a) Complete a Punnett square showing all possible genotypes of their offspring. b) What is the probability of this couple producing a child with blue eyes? c) What is the probability of producing a child who has both brown eyes and a smooth hairline?
12. A heterozygous agouti mink is bred with a true-breeding white mink. Of the three offspring, one is an agouti male, one is a white male, and one is a black female. What is thesimplest explanation as to coat colour inheritance in these mink? the agouti allele is sex-linked a single gene is involved with the agouti allele being dominant a single gene is involved with the white allele being recessive at least two genes are involved
1. In guinea pigs, two different genes affect the coat. One gene codes for coat color and there are 2 codominant alleles C1=Brown and C2=White. The heterozygous form is tan colored. The second gene codes for presence of hair with H=hairy (dominant) and h=hairless (recessive). If we didn't know the genotypes of the parents, but mom is hairless and dad is tan haired, and the babies produced included brown, tan, white, and hairless, can you guess the genotypes of the parents? Show your work below (explain how you came up with the answers)
5A. In shorthorn cattle, the polled condition is dominant over horned. Also, the heterozygous condition (RW) of red coat (R) and white coat (W) is roan, an example of codominance. (The roan coat contains both red and white fur because neither allele is dominant over the other). If a homozygous polled, white male is bred to a horned, red female, what will be the appearance of the F1 generation? Horned: r: Roan Coat: a.

4. The ruffed chicken has an under-chin wattle. A smooth wattle (S) is dominant over a wrinkled wattle (s). A red wattle (HR) is incompletely dominant with a white wattle (HW) so that an individual with HRHW will have a pink wattle. A chicken with a wrinkled red wattle is mated to a homozygous chicken with a smooth white wattle. What is the genotype and phenotype of the chicks?
3. Short-tailed pup distribution. In mice, the dominant T allele results in a short tail. Homozygous T/T genotype is lethal, which means mouse embryos with this genotype die before they are born. Homozygous t/t is normal, with normal tail. A cross between two short-tailed mice produces a litter of 5 pups. a). What are the genotype(s) of the two short-tailed mice used in the cross? b). What are the possible genotypes and phenotypes of the 5 pups? What are their perspective ratio?
4. In humans, cystic fibrosis and albinism are both inherited as independently assorting autosomal recessive traits. Use fto represent the recessive allele for cystic fibrosis and Ffor the allele for the unaffected condition. Use A to represent the dominant allele for normal melanin man is albino and heterozygous for cystic fibrosis. His wife has the unaffected phenotype for both traits, although her father had cystic fibrosis and a for the recessive allele for albinism. and her mother is albino. 4a. What is the genotype of the wife? 4b. What is the probability that a child of this couple is albino and has cystic fibrosis?
8. In certain breeds of dogs, two different sets of alleles determine the color pattern. Black color is dominant and red color is recessive; solid color is dominant and white spotting is recessive. A homozygous black-and-white spotted male is crossed with a red-and-white spotted female. What is the probability of their producing a solid black puppy? Show your work.
1. In pea plants, yellow color (Y) is dominant over green color (y). A yellow-colored pea plant is crossed with a green-colored pea plant. Half of their offspring is yellow-colored while the other half is green-colored.What is the genotype of the yellow-colored parent? YY O Yy yy The genotype cannot be determined. 2. A scientist discovered an unknown organism in a tropical rainforest. The organism has been identified to possess the following characteristics: (1) multicellular at some point of its life cycle; (2) feeds on decaying organic matter; and (3) has a cell wall made of chitin.Which Kingdom does the unknown organism likely belong to? Kingdom Animalia Kingdom Plantae Kingdom Fungi Kingdom Protista 3. Which statement about ferns is TRUE? Ferns are unicellular organisms. Ferns are nonvascular plants. O Ferns have spores as reproductive structures. Ferns are capable of secondary growth.
4. J. A. Moore investigated the inheritance of spotting patterns in leopard frogs. The pipiens phenotype had the normal spots that give leopard frogs their name. In contrast, the burnsi phenotype lacked spots on its back. Moore carried out the following cross, producing the progeny indicated. Parent phenotypes burnsi x burnsi Progeny phenotypes 39 burnsi, 6 pipiens a. What are the likely genotypes of the two parents? Be sure to specify the dominant and the recessive trait. b. Use a chi-square test to evaluate the fit of the observed numbers of progeny to the number expected on the basis of your proposed genotypes.
