The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
Holstein cattle suffer from the condition citrullinemia, in which homozygous recessive calves die within a week of birth because they cannot break down ammonia that is produced when amino acids are metabolized. If a cow that is heterozygous for the citrullinemia gene is inseminated by a bull that is homozygous dominant, what is the probability that a calf inherits citrullinemia?
raccoons may have wide, medium-sized, or narrow bands around their tails. They may also havethe habit of washing all, or some of their food, or do not wash their food at all. a) assign genotypes to the phenotypes mentioned (see attached table) b. What mode of inheritance would most likely be exhibited by these traits if crosses were made? c. If two raccoons with medium-sized tail bands and have the habit of washing some of theirfoods will be crossed, what is the probability of having F1 raccoons with: c.1 wide tail bands that won’t wash any of their food? c.2 the same genotype as the parent raccoons? d. If a raccoon with a wide tail band that washes only some of its food is crossed with a raccoonwith a narrow tail band that doesn’t wash any food, what percentage of their offspring wouldbe medium-tailed and washes all its food? Show COMPLETE cross.
In oats, the color of the chaff is determined by a two-gene interaction. When a true-breeding black chaff plant was crossed to a truebreeding white chaff plant, the F1 generation was composed of allblack chaff plants. When the F1 offspring were crossed to eachother, the ratio produced was 12 black to 3 gray to 1 white. First,construct a Punnett square that accounts for this pattern of inheritance. Which genotypes produce the gray chaff phenotype? Second,at the level of protein function, how would you explain this type ofinheritance?
In Elves, curled toes (T) is dominant to flat toes (t). If an Elf that is heterozygous were crossed with an Elf that is homozygous recessive, what possible offspring could there be in the F1 generation?
Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Y allele are present, a green parakeet is produced. What is the percent probability of obtaining a yellow or blue parakeet when a heterozygous green parakeet is crossed with a white parakeet? Show all work including Punnett square and explanation. Record your answer as a whole number rounded to one decimal place.
Another type of monohybrid inheritance involves the expression of both phenotypes in the heterozygous situation. This is called codominance. One of the best-known examples of codominance occurs in the blue Andalusian chicken. "Blue" birds are heterozygous (BW) and result from the mating between a black bird (BB) and a white bird (WW). Blue birds do not really have blue feathers, instead having a mixture of black and white feathers that reflects light to appear blue. Thus, the "blue" coloration is not a consequence of blending of the pigments (after all, the mix is not gray) but rather the result of both colors existing on the same bird. That is both phenotypes occur on the same individual. a. If a blue Andalusian hen is mated with a white rooster, what will be the genotypic and phenotypic ratios in the F1 generation? Genotypic ratio- Phenotypic ratio- b. List the parental genotypes of crosses that could produce at least some: White offspring- Black offspring
Duroc Jersey pigs are typically red, but a sandy variation is also seen. When two different varieties of true-breeding sandy pigs were crossed to each other, they produced F1 offspring that were red. When these F1 offspring were crossed to each other, they produced red, sandy, and white pigs in a 9:6:1 ratio. Explain this pattern of inheritance in terms of number of genes, and any allele or gene interactions.
In the Mexican hairless breed of dog, the lack of hair corresponds to the H/h genotype. Normal dogs (with hair) are homozygous h/h for the recessive allele. Puppies H/H are stillborn and they display severe muzzle abnormalities and a lack of inner ear. a) Which crosses can give hairless dogs at the next generation ? b) Which one gives the highest frequency of hairless dog for a breeder (only viable animals will be taken into account)?
A homozygnous Dominant brown mouse is crossed with a heterozynous Brown mouse(tan is ressesive color)
Labrador retrievers are black, brown, or yellow. In a cross of a black female with a brown male, results can be all black puppies, 1/2 black to 1/2 brown puppies, or 3/4 black to 1/4 yellow puppies. These results indicate what about the inheritance pattern of fur color in Labrador retrievers, and why does this occur? What is known about the genes that control fur color in Labrador retrievers
In mice, albinism (g) is recessive to grey coat colour (G). A grey mouse mated with an albino mouse. Over the course of several months, 38 pups were born. Out of 38 pups, 17 had a grey coat, and 21 were albino. Theoretically, what is the expected result from the parental cross of a grey mouse and an albino mouse, and why does the expected result not match the result stated in the information given above? a. Theoretically, there should be a 3:1 ratio of grey mice to albino mice, or 29 grey coat mice and 9 albino mice. With more litters, the actual results would match the expected results more closely. b. Theoretically, there should be a 1:1 ratio of grey mice to albino mice, or 19 grey coat mice and 19 albino mice. With more litters, the actual results would match the expected results more closely. c. Theoretically, 100% of the mice should have grey coats so all 38 offspring should have grey coats. There was an experimental error that can account for the deviation. d.…
