3. Red-green color blindness is caused by an X-linked recessive allele. Suppose a color-blind man and a woman with normal vision and no family history of color blindness married and had a daughter who was color blind and had Turner syndrome. Explain how this could happen citing which parent(s) could be responsible and where NDJ could occur. You will need to show how this would work for the NDJ in a diagram.

Choose the statement that is incorrect. a. A son can inherit a recessive allele on an X chromosome from either parent. b. An individual may inherit three or more of each type of chromosome characteristic or the species, a condition called polyploidy. c. A female child inherits one X chromosome from her mother and one from her father. d. Pedigree analysis can be used to determine a future childs chance of being born with achcondroplasia.
In cats, the genotype AA produces tabby fur color; Aa is also a tabby, and aa is black. Another gene at a different locus is epistatic to the gene for fur color. When present in its dominant W form (WW or Ww), this gene blocks the formation of fur color and all the offspring are white; ww individuals develop normal fur color. What fur colors, and in what proportions, would you expect from the cross AaWw Aa Ww?

1. A mother with blood type A has a child with blood type O, and she claims that Mister X is the father. Mister X denies that he could possibly be the father, because he has blood type B. If you were the judge presiding over this case, which of the following arguments would you find most convincing? a. Mr. X could be the father if his blood genotype is IBIB, and the mother’s blood genotype is IAIA b. Mr. X cannot be the father because a child with blood type O cannot have a parent with blood type B c. Mr. X could be the father if his blood genotype is IBi, and the mother’s blood genotype is IAi d. Mr. X cannot be the father because a parent with blood type B cannot have a child with blood type O e. Mr. X cannot be the father because the human ABO blood types are sex-linked traits 2.

If a man who is heterozygous for tongue rolling marries a woman who is heterozygous, what would you predict for the genotypes and phenotypes of their children?
13. A dominant x-linked allele (B) gives normal color vision but the recessive allele (b) causes red-green color blindness.A.

If a woman who is colorblind marries a man with normal vision, what would you expect for the genotypes and phenotypes of their children? D. If a man is color-blind, which parent did he inherit the gene from? Explain your answer. E. Which parent does a man get all his x-linked genes from? F. If a woman is color-blind, what do you know about the genotypes and phenotypes of her parents? G. Are men more likely than women to get a genetic disease which is x-linked and dominant? Are they more likely to get a disease that is x-linked and recessive? Explain your answers. H. Can a man with normal color vision have a colorblind daughter? Explain your answer.…

2.In dogs, there is a hereditary deafness caused by a recessive allele, d. A kennel owner has a male dog that she wants to use for breeding purposes if possible. The dog can hear, but the owner is unsure of the genotype. She does a testcross (crosses it to a homozygous recessive dog), and two of the five offspring are deaf. This means that the male dog A.has the genotype DD B.has the genotype Dd C.is still of unknown genotype since there were offspring of both deaf and hearing phenotypes. D.has the genotype dd
4. Marfan syndrome is a genetic trait caused by in a dominant allele. The trait causes a weakening of the aorta that can be fatal. A teenager whose mother has the syndrome (but whose maternal grandfather was not affected), and whose father was unaffected, is concerend that she may have the trait. a. What is the phenotype of each of her parents? Genotype? b. What is the chance that the teenager has Marfan syndrome?
