- If 83% of the Elmo Muppet population has a condition that makes them refer to themselves in the third person, and you know that this condition is the result of the homozygous recessive genotype (ee)… You allow the Elmos to reproduce for a while and discover that in the heterozygous condition, the Elmos are capable of referring to themselves in the 3rd person, but only do so upon request. The PBS station puts out a casting call for a locally-produced Sesame Street. This is your chance to make a little cash with all the Elmos you have in your basement. It turns out, however, that the heterozygous Elmos are strongly preferred by the production crew, since they can turn off the third person self-references. So: EE Elmos are NOT acceptable actors, Ee Elmos are preferred actors, and ee Elmos are acceptable, but only when Ee Elmos are unavailable. If having a gig on Sesame Street is critical to Elmo survival: rank the fitness levels of the three genotypes and discuss whether/how long the E…Suppose that goats have one gene that codes for color, where A is brown and a is white. The goats also have another gene that codes for height, where B is tall and b is short. If these two genes are unlinked, what is the probability that a cross between Aa Bb × Aa bb parents will produce two out of six offspring that are brown and short? Provide answer as a decimal, rather than as a percentage.What will be the phenotypic ratio of the offspring of a purebreed male fly with eosin eyes (CCXw-eY) mated to a red-eyed female who is heterozygous for both the cream (C) and eosin eyes (Xw-e) allele.
- In a population of martians the hair color (H= purple or h=green) and eye-color (E=red or e=yellow) are very close together on the same chromosome. One heterozygote male, who knows that his dad was homozygous dominant and his mom had green hair and yellow eyes is considering fertilizing a homozygous recessive female. How many green-haired yellow-eyed offspring (out of 16) would they expect to have?Erminette fowls have mostly light colored feathers with an occasional black one, giving a flecked appearance. A cross of two erminettes produced a total of 48 progeny, consisting of 22 erminettes, 14 blacks and 12 pure whites. What genetic basis of the erminette pattern is suggested? How would you test your hypotheses?Based on the information you discovered in the previous problem, answer the following:a. A female fruit fly with genotype Tt nn is mated toa male of genotype Tt Nn. What is the probabilitythat any one of their offspring will have normalphenotypes for both characters?b. What phenotypes would you expect among the offspring of this cross? If you obtained 200 progeny, howmany of each phenotypic class would you expect?
- Female pig Emmy Lou (straight tail, white-haired) with the haplotype cH/Ch was mated to a curly-tailed black-haired male pig Wilhelm (ch/ch). Curly tails are due to the cc genotype and black hair is due to the hh genotype. From the choices shown below, which genotype would you expect to be the most frequent among their offspring? cH/ch cH/ch CH/ch CH/ch ch/ch ch/ch cc/hh cc/hh All genotypes are equally likely. All genotypes are equally likely.Suppose a species of tulip has three alleles for the gene that codes for flower color. The CR allele produces red tulips, the CB allele produces blue tulips, and the CW allele produces white tulips. Both CR and CB are dominant over CW, but CR and CB are incompletely dominant with each other, so CRCB heterozygotes have purple flowers. What is the expected phenotypic ratio in the offspring of the following crosses, in the order red : blue : purple : white? Enter your answers as the most simplified ratio (e.g. 1 : 2 : 1 : 1 instead of 2 : 4 : 2 : 2). Enter 0 if none of the offspring from a cross will be a particular color. CRCB × CBCW _____ red : ______blue : ______purple : ______white CRCB × CRCW - _______red : _____blue : _____purple : _____white CRCW × CBCW - _____red : _____blue : _____purple : _____white CRCB × CRCB - red : blue : purple : whiteIn humans, the genetic disease cystic fibrosis is caused by a recessive allele (a). The normal (healthy) allele is dominant (A). What is the genotype of someone who has cystic fibrosis? What are the two different genotypes that a healthy person could have? If two people were both heterozygous for the cystic fibrosis gene, what fraction of their children would be likely to have this disease? Hint: Draw a Punnett square to figure it out.
- In rabbits, black hair depends on a dominant allele, B, and brown hair on a recessive allele, b. short hair is due to a dominant allele, S, and long hair to a recessive allele, s. If a true-breeding black short-haired male is mated with a brown long-haired female, describe their offspring. What will be the genotypes of the offspring? If two of these f1 rabbits are mated, what phenotypes would you expect among their offspring? In what proportions?In garden peas, long stems are dominant to short stems, and yellow seeds are dominant to green seeds. 100 long/yellow pea plants, all of which had one short/green parent, are interbred (bred to each other). 1600 progeny result. Please answer the following questions about these progenies. A. Assuming that these two genes are unlinked, about how many long/green pea plants would you expect to find among the offspring? B. What ratio of yellow to green seed color would you expect among the offspring? C. What would you expect the overall phenotypic ratio among the 1600 offspring to be (taking into consideration both traits)?Gene S controls the sharpness of spines in a type of cactus. Cactuses with the dominant allele have sharp spines, whereas homozygous recessive cactuses have dull spines. At the same time, a second gene, N, determines whether or not cactuses have long or short spines. Homozygous recessive cactuses have short spines. A cross between a homozygous sharp-long cactus and a dull short-spined cactus would produce what percentage of sharp-long cacti?
