- QUANTITATIVE Recall that hemophilia is an X-linked recessive disease. If a woman with hemophilia had children with a man without hemophilia, what is the chance that their first child will have the disease? What is the chance that their first child will be a carrier?Give typing answer with explanation and conclusion Suppose a woman who is homozygous for Huntington's disease has 12 children? We would expect __________ of them to have the disease. A mother who is heterozygous for the Huntington's disease gene wants to have a baby with a man who is also heterozygous for the gene. What is the likelihood their baby will not have Huntington's disease?Give typed full explanation The Genes you are examining exhibit a continuous pattern of variation. For these Genes, a Dominant Allele represents a 1 foot increase in overall height. If you cross the following individuals, AaBb and AaBb, what percentage of the offspring will be 7 feet tall. Assume an individual with no Dominant Alleles (aabb) is 4 feet tall. Report your answer as a percentage i.e., 22.1%.

If this trait is in Hardy-Weinberg equilibrium, approximately how many people are carriers?Karyogram and Identification of Chromosomal Aberrations List down five human chromosomal aberrations. Give the corresponding karyotype for each type then briefly describe the traits of affected individuals.Give typing answer with explanation and conclusion Red/green colorblindness is inherited as an X-linked recessive trait in humans. A woman with normal vision, whose father was colorblind, marries a man with normal vision. Predict the color vision of their sons and daughters. Provide a probability for each offspring, depending on their sex. Write a pedigree consistent with this inheritance.
- Give typing answer with explanation and conclusion What is the expected (predicted) frequency of the A2 allele if it is observed that 26 individual have the homozygous dominant genotype, 62 individuals have the heterozygous genotype and 75 individuals have the homozygous recessive genotype?Give typing answer with explanation and conclusion The father of Mr Spock, first officer of the starship Enterprise, came from planet Vulcan; Spock’s mother came from Earth. A Vulcan has pointed ears (P), adrenals absent (A), and a right-sided double heart (R). All these alleles are dominant to Earth alleles. The three loci are autosomal, and they are linked as shown: --P----- 15 mu -----A-------- 20 mu --------R— Here's the new twist: having Vulcan adrenals and a human heart is an embryonic lethal combination, which will distort the proportion of the various phenotypes. If Mr Spock marries an Earth woman and there is no genetic interference, what proportion (0…1.0) of their children will have the phenotypes: A. Human ears, Vulcan heart, human adrenals B. Human ears, human heart, Vulcan adrenals C. Vulcan ears, Vulcan heart, Vulcan adrenals D. Vulcan ears, human heart, human adrenalsQuestion:- Based on your selected mode of inheritance, show the genotypes for the following individuals. [Use these symbols for alleles: if it is autosomal, then use the symbols B - dominant, b - recessive (e.g. BB, bb etc.) if it is X-Linked, then X(B) - dominant, X(b) - recessive, and Y for Y-chromosome (e.g. X(B)X(B), X(B)Y etc.) ] I-1 I-2 II-7 II-8 III-10 III-11 III-12 IV-8 IV-9

Determine the genotypes of the parents and their children when albino male and normal femalePls answer the very last question. “ suppose that lll-2 and lll-5 were to have a child. What is the probability that their first child will be have the disorder?”Working with the definitions of penetrance and expressivity, analyze the following pedigree and assume that the father of the proband is homozygous for a rare trait. (Consider a rare trait here to be less than 1 in 30,000.) What pattern of inheritance other than autosomal recessive could explain this pedigree? In particular, explain the genotype and phenotype of the proband (arrow).
