Problems Involving Two Genes. A man with dark (dominant), curly (see problem I.5.) hair marries a woman with light, straight hair. Their daughter, who happens to have dark hair, marries a man with light, wavy hair. Answer the following questions about this dark-haired daughter and her family.
gene for antenna length is 5% (i.e. the genetic distance between them is 5 centimorgans). List all possible recombination frequencies between the gene for color and the gene for antenna length.
20 cze 2023 · Design a series of crosses to determine the map distance between these two loci. You can start with any genotypes you want, but be sure to specify the phenotypes of individuals at each stage of the process.
Use the distance matrix from part 1 as the basis for constructing a phylogenetic tree for the sequences A, B, C, and D. Specifically, add sequence labels (B, C, D) to the tree outlined below in the correct positions (I have already indicated the position of A).
• Mapping reveals the relative order of genes, not the actual physical distance. • The most accurate maps are made by summing the genetic distances of genes lying close together (small intervals). One needs to connect genes that lie far apart through the genes that lie between them.
1. i) What is the most likely mode of inheritance for this pedigree? Autosomal dominant. ii) State the genotypes of individuals # 1-5 in the following table using the letter ”A”. Use the uppercase letter to represent the dominant allele and lowercase letter to represent the recessive allele.
Calculate a genetic distance matrix for the sequences. Based on these values, which tree ( A, B, or C) do you think is best under the Genetic Distance criterion? Determine the minimum number of mutations required under the parsimony criterion for each of the three trees. Which is the most parsimonious tree? Here’s the best way to solve it.
