Solved in 2 steps
- As it turned out, one of the tallest Potsdam Guards had an unquenchable attraction to short women. During his tenure as guard, he had numerous clandestine affairs. In each case, children resulted. Subsequently, some of the childrenwho had no way of knowing that they were relatedmarried and had children of their own. Assume that two pairs of genes determine height. The genotype of the 7-foot-tall Potsdam Guard was A9A9B9B9, and the genotype of all of his 5-foot clandestine lovers was AABB. An A9 or B9 allele in the offspring each adds 6 inches to the base height of 5 feet conferred by the AABB genotype. a. What were the genotypes and phenotypes of all the F1 children? b. Diagram the cross between the F1 offspring, and give all possible genotypes and phenotypes of the F2 progenyIn basic eye color in humans, brown (B) is dominant to blue (b). A brown-eyed man, whose father was brown-eyed and whose mother was blue-eyed, married a blue-eyed woman whose father and mother were both brown-eyed' The couple has a blue-eyed son. For which of the individuals mentioned can you be sure of the genotypes? What genotypes are possible for the others?Human blood types show both codominance and multiple alleles. The blood types are A, B, AB, and O. The alleles for A, B, and O are IA, IB, and i respectively. A and B are codominant, and O is recessive. Is it possible for a female with type AB blood and a male of type O to have a baby with AB blood?
- In a certain animal, black coat (B) are dominant to white coat (b). In a genetic cross of two animals that are heterozygous for coat color, what is the probability of having white coat? Write in fraction formIn rabbits, the gene for fur color is multiallelic. Agouti (C) is dominant to chinchilla (Cch), chinchillas is dominant to himalaya (Ch), and himalaya is dominant to albino (c). Determine the genotypes of each corresponding phenotypes. Please show the solution.In rabbits, white coat color (CW) and black coat color (CB) are codominant, and both of these alleles are dominant over albino (c); heterozygotes (CWCB) are spotted. Consider a cross between a heterozygous black-coated rabbit and a homozygous white-coated rabbit.
- In birds, wingspan is determined by two genes, one with complete dominance of one allele over the other, one with additive effects. Birds with genotype aabb has 16 cm long wingspan, whereas those with AABB has 20 cm long wingspan. A cross between AABB and aabb parents produced F1 with 19cm wingspan. Crossing the F1s produced F2 with the following phenotypes (in cm): NOTE: In a normal distribution of values, 68% of them will fall within the range of the mean less one standard deviation and the mean plus one standard deviation. Compute for: a. compute for number of classes b. compute for the range c. compute for the intervalIn roan bulls, alleles for both red and white hair are codominant (BRBW). What is the percentage of genotype and phenotype if a roan cattle is bred to, (a) a homozygous red cow (BRBR), (b) a heterozygous white cow (BWBw).Cystic fibrosis is an autosomal recessive disease characterized by two copies of a mutated CFTR gene. If one in 100 (hypothetical scenario, not reality) people in the United States have cystic fibrosis, calculate the p and q frequency for the normal allele (p) and the mutated allele (q). Based on those calculations, what percentage of individuals would be expected to be homozygous dominant?
- In the shorthorn breed of cattle, The red and white coat colors are codominant with each other with the resulting hit rosagas condition being roan. A breeder has some white, some Roan, and some red cattle (female) And only one round bull (male).  A. What color cow would be bread to the ro bowl to guarantee the best chance of having white offspring? B. What is the probability of a red cow cross with the Roan bull resulting in a white half? explain by using parent and possible offspring genotypes.  C. What is one possible way that the farmer can guarantee having over red offspring by going outside of his breeding stock? Explain by using parent and possible offspring genotypes. Vulcans have pointed ears (determined by allele P), absent adrenals (determined by A), and a right-sided heart(determined by R). All these alleles are dominant to normal Earth alleles: rounded ears (p), present adrenals (a),and a left-sided heart (r). The three loci are autosomaland linked as shown in this linkage map:10 m.u. 25 m.u.P A RMr. Spock, first officer of the starship Enterprise, has aVulcan father and an Earthling mother. If Mr. Spock marries an Earth woman and there is no (genetic) interference, what proportion of their children will havea. Vulcan phenotypes for all three characters?b. Earth phenotypes for all three characters?c. Vulcan ears and heart but Earth adrenals?d. Vulcan ears but Earth heart and adrenals?Phenylketonuria (PKU) is a disorder caused by a recessive allele. Two carrier individuals have progeny. If they have a normal child, what is the probability that he or she will be heterozygous? Show solutions.
