17. What is a pedigree? How would you read a pedigree? b.Determine whether the trait is dominant or recessive. If the trait is dominant, one of the parents must have the trait. ...Determine if the chart shows an autosomal or sex-linked (usually X-linked) trait. For example, in
18. What is an autosomal recessive allele? 19. What is an autosomal dominant allele? 20. What is an sex linked recessive allele? Genetics Problems 1. Determine all the possible gametes that the following individuals could produce: CC FfGg MMNnOOdd Ee FFGGXxYyZz AABb2. In dogs, wire hair is due to a dominant gene, W, and smooth hair is due to its recessive allele,w. A)If a homozygous wire haired dog is mated with a smooth haired dog, what type of offspring (F1 generation) could be produced? Give genotypes, phenotypes and the ratios of each.B)What type of offspring could be produced in the F2 generation. Give genotypes, phenotypes and the ratios of each.C)A wire haired male is mated with a smooth haired female. The mother of the wire haired male was smooth What types of offspring would be produced? Give genotypes, phenotypes and the ratios of each.3. In dogs, black fur is controlled by the dominant allele, B, and brown by its recessive, b. Give the genotypes of the parents and offspring of a cross that produces 1⁄2 black pups and 1⁄2 brown pups.4. Cross a homozygous dominant tall, TT, pea plant with a short homozygous pea plant, tt. How many short pea plants will appear in the offspring of this cross (F1)? If you cross these offspring,what will the F2 offspring be? Give genotypes, phenotypes and the ratios of each.5. A homozygous type A blood male marries a heterozygous type B blood female. What are the chances of generating a type O child from this cross? Give the phenotypes, genotypes and the ratios of each.
