Rama the cama, a llama-camel hybrid, was born in 1998. The idea was to breed an animal that has the camel's strength and endurance, and the llama's gentle disposition. However, instead of being large, strong, and sweet, Rama is smaller than expected and has a camel's short temper. The breeders plan to mate him with Kamilah, a female cama. What potential problems with this mating should the breeders anticipate?

- In the United States, the rare red wolf (Canis lupus) has been known to hybridize with coyotes (Canis latrans), which are much more numerous. Although red wolves and coyotes differ in terms of morphology, DNA, and behavior, genetic evidence suggests that living red wolf individuals are actually hybrids. Red wolves are designated as an endangered species and hence receive legal protection under the Endangered Species Act. Some people think that their endangered status should be withdrawn because the remaining red wolves are hybrids, not members of a "pure" species. Do you agree? Why or why not?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 males and two females. One male and one female cub have normal spots and one each have dark spots. What is the genotype of the mother? 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)? Will any of the cubs from this latest cross have dark spots?Cockroaches from the dormitories at Texas A&M University usually weigh about 1 gram. However, about 100 miles west of the university is a colony of much larger cockroaches in which some individuals obtain a weight of as much as 25 grams. These cockroaches of unusual size (COUS) have apparently evolved to consume the large supply of garbage that exists in the region. If a 25-gram cockroach is crossed with a 1-gram cockroach, their progeny grow uniformly to a size of about 13 grams. If two of these 13-gram (F1) cockroaches are crossed, cockroach sizes from 1 gram to 25 grams are produced. However, the 1-gram and the 25-gram cockroaches are rare, occurring at a frequency in each case of about 1 in 64. If a 13-gram F1 cockroach is crossed with a 1-gram cockroach, how frequently are 9-gram cockroaches expected? Cockroaches from the dormitories at Texas A&M University usually weigh about 1 gram. However, about 100 miles west of the university is a colony of much larger…
- In rural northeast Kansas domesticated cats are becoming wild, and biologists are observing that wildcats occur in three colors. Fur color is controlled by a single gene that exhibits incomplete dominance. A homozygous dominant cat is blue (BB), a homozygous recessive cat is red (bb), and a heterozygous wildcat will be purple (Bb). What would be the expected phenotypes of the offspring if a blue wildcat mates with a red wildcat? Develop a Punnett square and list the genotypes as well.In cats, white patches are caused by the dominant allele P, while pp individuals are solid-colored. 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-colored and short-haired mates with a short-haired, solid-colored cat whose mother was long-haired and solid-colored. What kinds of kittens can arise from this mating, and in what proportions? Show your solution. Explain your answers.Clouded leopards are a medium sized, endangered species of cat, living in the very wet cloud forests of Central America.

- In a species of dog, plaid color is represented by P and purple by p, short -tailed is T and long-tailed is t.

PpTT & PPTT pptt & PPTT short-tailed purple & long tailed plaid male: purple w/ long tail & female: plaid w/ short tailStickleback fish that are deep in the ocean can experience a mutation wherein they experience a "loss-of-function" of their spikes. Heterozygotes actually look the same as homozygous wild types at this depth. If a homozygous deep-water wild type stickleback mated with a homozygous shallow-water wild type, what phenotypes would you expect to see?When a yellow female Labrador retriever was mated with a brown male, half of the puppies were brown and half were yellow. The same female, when mated with a different brown male, produced only brown offspring. Explain these results.
- You are studying three traits in a goldfish variety; body colour (A or a), tail length (B or b) and shape (C or c). Note: Use the uppercase letters for the alleles associated with the dominant phenotypes and the lowercase letters for the alleles associated with the recessive phenotypes. Assume that each of these traits is regulated by one gene. Photo credit https://www.petmd.com Part A. You mate a gold fish (P1) with a white fish (P2) and obtain 100 fish in F1, of which 50 are gold and 50 are white. Write two sets of the possible genotypes of the parental and the resulting F1 fish by filling in the table below. Sets P1 P2 F1 gold fish F1 white fish 1 2 Part B. You cross a true breeding gold fish having long curly tail (P3) with a true breeding gold fish having short and straight tail (P4). All of the resulting F1 fish have long straight tails. Write the genotype of the parental fish (P3 and P4) using the outlined nomenclature.…Two distinct phenotypes are found in the salamander Plethodon cinereus: a red form and a black form. Some biologists have speculated that the red phenotype is due to an allele that is dominant over an allele for black. Unfortunately, these salamanders will not mate in captivity, so the hypothesis that red is dominant over black has never been tested. One day, a genetics student is hiking through the forest and finds 30 female salamanders, some red and some black, laying eggs. The student places each female with her eggs (about 20 to 30 eggs per female) in a separate plastic bag and takes them back to the lab. There, the student successfully raises the eggs until they hatch. After the eggs have hatched, the student records the phenotypes of the juvenile salamanders, along with the phenotypes of their mothers. Thus, the student has the phenotypes for 30 females and their progeny, but no information is available about the phenotypes of the fathers. Explain how the student can determine…Clouded leopards are medium-sized, endangered species of cat, living in the very wet cloud forests of Central America.
