15. A factor A is essential for sight and the factor B results in blindness no matter what other genes are present. Determine the ratio of blind to normal offspring from a cross aaBb X AaBb. Be sure to explain the nature of this kind of inheritance.

Suppose that the " fabulous " phenotype is controlled by two independent genes, A and B, as shown in the diagram below. Allele A encodes a functional enzyme 1, which converts " lain " to " smashing ". The recessive allele a encodes a nonfunctional Enzyme 1. Allele B encodes a functional Enzyme 2, which converts " smashing " to " fabulous ". The recessive allele B encodes a functional and B genes are both autosoaml and assort independently. A...

D. 25% orme condition. The male is XX and the female is XY. But X-linked genes have the same effects in mugwumps as in humans. A recessive X-linked allele "n" produces red-green color blindness. The dominant allele "N" produces normal color vision. If a female mugwump with normal color vision mates with a male mugwump, phenotypically normal for color vision but whose mother was color blind, what is the probability that a son from that mating will be color blind?...

PART B. TWO-GENE CROSSES. Review the phenotype ratios for crosses between two unlinked genes (with traditional Mendelian ratios). The results for crosses involving two gene mutations are provided. There are three listed. You should choose 2 two-gene crosses to investigate. Determine if these mutations have any lethality, linkage, or epistatic relationship. Hint: A good first step is to look at the inheritance patterns of each individual gene. Typical Steps for Two-Gene Analysis. Various crosses have been performed and the results...

chup is called the bleeder's disease because the affected person's blood is unable to clot. nougn hemophiliacs do bleed externally after an iniury they also suffer from internal bleeding pa around joints. Hemorrhages can be checked with transfusions of fresh blood (or plasia U protein. The most common type of hemophilia is hemophilia A, due to the absence or minimal presence of a particular clotting factor called...

Suppose that the "Green" phenotype is controlled by two genes, A and B, as shown in the diagram below. Allele A' produces enough enzyme 1 to convert "White" to "Red." Allele 'a' produces no enzyme 1. Allele 'B' produces enough enzyme 2 to convert "Red" to "Green." Allele 'b' produces no enzyme 2. The A and B genes are both autosomal and assort independently.
