- Congenital hypertrichosis (CH) is a very rare X-linked dominant inherited condition. CH is characterized by the growth of dark hair over the body. CH is so rare, only 50 cases have been identified since the Middle Ages. The incidence of this condition is considerably higher in a small Mexican village (from which the partial pedigree below is derived) than the rest of the human population. I II III Use the following information to answer the two questions. IV D II-4 8 9 IV-6 0=10~ 11 1. Using appropriate nomenclature, identify the genotypes for the following 2 individuals: 12 13 your response must include an appropriate legend/key to identify allele symbols. 2. Show how a Punnett square (using the allele symbols from the previous question) is used to determine the probability in percent of individuals III-11 and III-12 next offspring has CH?The picture below represents a G1 cell from a newly discovered species that uses the X/Y sex determination system. Alleles for the different autosomal genes of interest are indicated on the chromosomes, and genes R and T are 36 cM apart. Red lines show maternal chromosomes, and blue lines show paternal chromosomes. Answer the following questions about this individual. a) This individual can produce a pool of different gametes. List any TWO potential gametes that will occur at different frequencies. Give the alleles of each gamete contained within a set of brackets, and indicate the expected frequency (up to two decimals) at which that gamete would occur. b) Name any two loci in this individual that can result in recombination in the gametes via the process of independent assortment. c) What is the sex of this individual? Justify your answer. d) Give the term that will describe the morphology of the chromosome that carries the R/T alleles. e) Provide the genotype of the fertilizing male…Given the karyotype shown at right, is this a male or a female? Normal or abnormal? What would the phenotype of this individual be?
- In com, male sterility is controlled by maternal cytoplasmic elements. However, the presence of a nuclear fertility restorer gene (F_) restores fertility to male sterile lines. Using the following cardboard chips, simulate the crosses indicated below. Present your cross to your instructor for checking. After being checked, draw your simulated crosses in the spacesprovided below. Give the genotypes and phenotypes of the offspring in each cross, and properly label the nucleus and the cytoplasm of each individual in the crosses.Big white circular chips Male sterile cytoplasmBig peach circular chips Male fertile cytoplasmSmall peach circular chips FF nucleusSmall half-white-half-peach circular chips Ff nucleusSmall white circular chips ff nucleus a. male sterile female x FF maleExplain your results. b. male sterile female x Ff maleExplain your results.For this problem, use the information given in problem 15. A young woman with blood type O gave birth to a baby with blood type O. In a court case, she claims that a certain young man is the father of her child. The man has type A blood. Could he be the father? Can it be proven on this evidence alone that he is the father? ^Need answers to that one, including genotype, phenotype gametes and punnett square. This is question 15 as a little background dont need this solved . In humans, there are three alleles for blood type: A, B, and O. The allele for blood type A and the allele for blood type B show incomplete dominance. A person with both alleles has blood type AB. Both A and B dominate type O. A person with alleles for blood types A and O marries someone with alleles for blood types B and O. List the types of blood their offspring could have and the probability for each blood type in the offspringDraw a Punnett square for the dihybrid cross described below (it is the same story as given for question 8, above) and use it to fill in the blanks correctly in the text that follows. NOTE: Please type in whole numbers, no symbols. There are two known alleles of gene occupying a specific locus in the X chromosome. The gene in question codes for a transcription factor involved in digit development. The mutant allele is dominant and gives rise to an additional but non-functioning little finger (polydactyly) on both hands. A couple have had their DNA sequenced at the region of interest, the male exhibits polydactyly because of the mutation, the female is homozygous wild type at the same locus and therefore has the wild type phenotype. Both have green eyes. In this story; eye colour shows a monogenic autosomal inheritance pattern and the allele for brown eyes shows incomplete dominance with that for blue eyes, the heterozygote phenotype is green eyes. The genes for eye colour and…
- What is the approximate percentage chance that individual V.2, shown in the pedigree diagram below will have inherited the X- linked recessive allele shown to be carried by his great-great-grandmother? Note: only type the number, not the percentage symbol. Answer: The chance that individual V.2 shown in the pedigree below has inherited the X-linked recessive allele shown to be carried by his great-great grandmother is approximately Blank 1 percent. 노 ㅍ먹이 12 I 마일 메인 de 먹어 요 58 ㅁ + ܡܐIn Drosophila, the genes ct(cut wing margin), y (yellow body), and v (vermilion eye color) are X-linked. Females heterozygous for all three markers were mated with wildtype males and the following male progeny were obtained. As is conventional in Drosophila genetics, the wild-type allele of each gene is designated by a “+” sign in the appropriate column. Use the data to (A) create a genetic map of the genes, (B) calculate interference, and (C) interpret the value of interference. Show your work.A woman diagnosed with early-onset Alzheimer's due to a mutation of the APP genehas children with a man that has no family history of familial Alzheimer's. Give the probability of each possible genotype with corresponding phenotype. (The woman has two possible allele combinations. You must show both possibilities)
- A homozygous fly with two recessive mutations causing purple body and short wings (ppss) is mated with a fly heterozygous for both mutations (p+p and s+s): "+" represents the wild-type allele. They have the following offspring: 26 Wild type (normal body, normal wings) 345 Purple body, normal wings 376 Normal body, short wings 13 Purple body, short wings What is the allele arrangement (haplotype) for the heterozygous parental fly?

Image with alt text: d) Double stranded D N A with top strand marked p plus and p, lower strand marked s plus and s. Item1,…A homozygous fly with two recessive mutations causing purple body and short wings (ppss) is mated with a fly heterozygous for both mutations (p+p and s+s): "+" represents the wild-type allele. They have the following offspring: 26 Wild type (normal body, normal wings) 345 Purple body, normal wings 376 Normal body, short wings 13 Purple body, short wings What is the allele arrangement (haplotype) for the heterozygous parental fly? ("p" designates the mutant allele; "p+" designates the wild-type allele.)In Drosophila, the X-linked recessive mutation vermilion (v) causes bright red eyes, in contrast to the brick-red eyes of wild type. A separate autosomal recessive mutation, suppressor of vermilion (su-v), causes flies homozygous or hemizygous for v to have wildtype eyes. In the absence of vermilion alleles, su-v has no effect on eye color. Determine the F1 and F2 phenotypic ratios from a cross between a female with wild-type alleles at the vermilion locus, but who is homozygous for su-v, with a vermilion male who has wildtype alleles at the su-v locus
