Assume that the m, a, and b genes are all linked but you don't need to calculate exact frequencies of each genotype/phenotype. Parental gametes will be m++ or +ab Recombinant gametes will be m+b or +a+ if there is a crossover between a and b Or mab and +++ if there is a crossover between m and a The most common categories will be combinations with the parental gametes m++ +a+ +ab m+b Scenario 1: +a+ wild-type m+b M-only +ab wild-type m++ M-only mab M-only +++ wild-type +a+ A-only m+b B-only +ab AB m++ wild-type mab AB +++ wild-type +a+ wild-type m+b MB mab MB +++ wild-type +a+ A-only m+b wild-type mab A-only +++ wild-type m + a mab +++ +a+ A-only m+b MB mab MAB +++ wild-type +a+ m+b mab +++ wild-type

Gene Interaction and Epistasis Hair color is due to the presence of melanin. There are two types of melanin produced by melanocytes. One is eumelanin, which is responsible for black (homozygous), brown (heterozygous), and blond (recessive) hair colors. The other is pheomelanin, which is responsible for red hair color. During melanin synthesis, MCR1gene converts pheomelanin to eumelanin. However, a variant of the MCR1 gene (MCR1variant), prevents this conversion. A cross between a blond-haired mother and a red-haired father produced 100% brown-haired children. When they came of age, one child married a double heterozygote, and both were blessed with 7 children; 2 with black hair, 2 with brown hair, 1 with blond hair, and 2 with red hair. Using the 7-step method, determine the genotypes of the P1, the F1, and the F2s. BOX your answers (if handwritten) or HIGHLIGHT your answers (if encoded).

Recessive epistasis: In a cross between fruit flies that are both double heterozygous for modifier gene and coat color, in the total offspring of 192, how many fruit flies have gray- coat, white coat, and black coat? A recessive allele blocks the expression of the coat color of fruit flies. Make a null hypothesis, compute for chi-square and determine if the null hypothesis is accepted or rejected.Show your answer, table, punnet square, and solution.

Question:- A) Give one domain.motif found in the SRY portion and state clearly how it leads to the development of the Wollfian system. B) Explain the genotype and the phenotype of an XY female and how such an individual could occur. C) Explain the genotype and the phenotype of an XX male and how such an individual could occur.
Question:- For a simple cross between a purple-flowered plant and a white-flowered plant, where purple is dominant over white. a. Show the F2 in a Punnett square. What are the proportions of genotypes and phenotypes? Express as fractions, decimal fractions and ratios. b. Now imagine that half of the pollen carrying the recessive allele die before reaching their target, while those carrying the dominant allele are unaffected; what are the proportions of genotypes and phenotypes now?What does this tell you about Mendel’s principle of segregation?
to only 23 rounds for a woman of age 20. That is a 6.5-fold greater number of cell divisions and proportionately greater opportunity for new point mutations. Yet, on average, 20-year-old men contribute only about twice as many new point mutations to their offspring as do women. How can you explain this discrepancy?
TOPIC: Variations in Gene Expression In a cross involving polygenic inheritance, three (3) gene pairs control plant height. The shortest and tallest plants are 12 cm and 24 cm, respectively. What height should all F1s display if the shortest and tallest plants were crossed, assuming environmental factors are the same
Equalizing the Expression of X Chromosome Genes in Males and Females Males have only one X chromosome and therefore only one copy of all genes on the X chromosome. Each gene is directly expressed, thus providing the basis of hemizygosity in males. Females have two X chromosomes, but one is always inactivated. Therefore, females, like males, have only one functional copy of all the genes on the X chromosome. Again, each gene must be directly expressed. Why, then, are females not considered hemizygous, and why are they not afflicted with sex-linked recessive diseases as often as males are?
Epistasis: 1) In violets, purple flower color (P) is dominant over white (p), but there is also a gene that determines if that pigment will be expressed in the petals of the flower. If the plant is “cc” then the purple pigment is not expressed in the petals of the flower, and the flower will be white anyway. a. A plant homozygous for both the purple flower and the control gene is crossed with a plant with white flowers and non-expressed pigment. What is the phenotype and genotype of the offspring in this cross? b. If the plants generated in “A” are allowed to self-pollinate, what is the expected phenotypic rations of the resulting offspring?
Cat fur coat color genetics is interesting. Orange fur is dominant (''B'') to black fur (''b'') and piebald, which is white spotting, is dominant (''S'') to non-white-spotted (''s''). Both of those genes are located on the X chromosome. In addition, in cats, somatic cells exhibit X-inactivation randomly, which explains why there are tortoiseshell cats (when heterozygous, have orange and black spots) as well as calico cats (orange and black but also with white spots). An orange and white spotted male is mated with a tortoiseshell female. Draw a dihybrid Punnet square to show the possible offspring:
Complementation tests of distinct recessive mutants, 1 through 8, produce the data in the matrix below. A plus (+) indicates complementation, meaning the phenotype of the combined alleles is wild type, and a minus (-) indicates a failure to complement meaning that a mutant phenotype results. Assume that the missing mutant combinations would yield data consistent with the entries that are shown. How many complementation groups are formed by these eight mutants?
