4. Clouded leopards are a medium sized, endangered species of cat, living in the very wet cloud forests of Central America. Assume that the normal spots (XN) are a dominant, sex-linked trait and that dark spots are the recessive counterpart. Suppose as a Conservation Biologist, you are involved in a clouded leopard breeding program. One year you cross a male with dark spots and a female with normal spots. She has four cubs and, conveniently, two are male and two female. One male and one female cub have normal spots and one each have dark spots. a) What is the genotype of the mother? b) Suppose a few years later, you cross the female cub that has normal spots with a male that also has normal spots. How many of each genotype will be found in the cubs (assume 4)? c) Will any of the cubs from this latest cross have dark spots? d) If so, how many and of what sex will they be?

1. Clouded leopards are a medium sized, endangered species of cat, living in the very wet cloud forests of Central America. Assume that the normal spots (XN)are a dominant, sex-linked trait and that dark spots are the recessivecounterpart. Suppose as a Conservation Biologist, you are involved in a clouded leopard breeding program. One year you cross a male with dark spots and a female with normal spots. She has four cubs and, conveniently, two are male and two female. One each of the male and female cubs have normal spots and one each have dark spots. What is the genotypeof the mother? 2. Assuming that after a few years, you cross the female cub that has normal spots with a male that also has normal spots. How many of each genotypewill be found in the cubs (suppose 4)
1. Honeybee workers undergo a resistant behavioral pattern called hygienic behavior. Susceptible worker genotypes failed to remove the diseased larvae, so that the disease spread easily throughout the honeybee colony. a) When inbred lines of resistant genotypes were crossed with inbred lines of susceptible genotypes, the F1 worker bees showed unhygienic behavior.Is hygienic behavior dominant or recessive in these bees? Why?
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…
2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
1. A gardener harvested 3,697 seeds from cross breeding a pure line red-flower petunia and pure line white-flower petunia. Then, he planted the harvested seeds in a 25x25 m plot. He was shocked that all of his planted petunias produced red flowers. Why? A. The red flower petunia is a dominant trait. B. The red flower petunia is a recessive trait. C. The white flower petunia is a dominant trait. D. The white flower petunia has a heterozygous genotype in flower color. 2. A veterinary doctor found a long tail female cat along the way going to her clinic. She wanted to know if the long tail female cat is a pure breed/line or not? So as a Biology student with genetic subject, which of the following choices can you correctly suggest to her? Considering the long tail trait as dominant trait. A. She must cross breed it with a short tail female cat B. She must do a back cross breeding with a short tail male cat C. She must run a molecular test for the long tail female cat…
About 7% of men in a population are red-green colour blind due to a sex-linked recessive gene. Assuming random mating in the population with respect to colour blindness b) What percentage of women would be expected to be heterozygous?
About 7% of men in a population are red-green colour blind due to a sex-linked recessive gene. Assuming random mating in the population with respect to colour blindness; so What percentage of women would be expected to be heterozygous?
Figure 19.2 In plants, violet flower color (V) is dominant over white (v). If p = .8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV), heterozygous (Vv), and homozygous recessive (vv)? How many plants would you expect to have violet flowers, and how many would have white flowers?
1. A male French Alpine (WwHH) is crossed with a female French Alpine (wwHh). Where W-White, w-gray, H-Horned, h-Polled. Give the phenotypic and genotypic ratio of their offspring. 2. A male Sahiwal (RRHH) is crossed with a female Angus (Rrhh). Where R-Red, r-Brown, H-Horned, h-polled. Give the phenotypic and genotypic ratio of their offspring.
1. A new species of animal called the rekamriliob has been found in the wild. The lab you work in has been tasked with studying its genetics. So far, there have been 2 main phenotypes found in the wild. Through selective breeding, your lab has determined that the gene for purple color (P) is dominant to the gene for golden color (p). Another lab has determined that the thick limb trait is dominant to the thin limb variety. If you breed a purebred purple thick limbed rekamreliob male with a golden thin limbed female, you get 100% thick limed offspring that are purple in color. If you take two of these organisms and breed them together, please predict the following. Assume that rekameliobs lay an average of 32 eggs. The gametes produced if the genes are unlinked b. genes The expected numbers of the possible phenotype in the offspring with unlinked The gametes produced if the genes are linked (list all possibilities, and show which ones are the result of crossing over) d. List the…
