Homework Answers
a)A two point mapping cross is generally done by the crossing of two parents one of which is homozygous for both the dominant alleles and one heterozygous for recessive alleles
b)For the offspring to have the expressed phenotypes as mentioned, parents should also show those phenotypic characters which are large and small and smooth and bumpy .The parental characteristics matching this combination is :
Large and smooth and small and bumpy

Just answer Part B
While working with a type of beetle that is normally smooth, large, and white, you discover three mutations that lead to the recessive phenotypes bumpy, small, and grey, respectively. You cross true- breeding smooth white beetles to true-breeding bumpy grey beetles and get all smooth white F1 beetles. Then you cross the F1 beetles to true-breeding bumpy grey beetles and, after analyzing 800 F2s, calculate a map distance of 5 M between the smoothness and color...

Calculate the theoretical probability of this cross producing each of the following phenotypes shown below. Record your answer as a full percentage for each phenotype as shown in the following order. Full colour: chinchilla: light grey: Himalayan: albino * Multiple alleles control the coat colour of rabbits. • The dominant allele, produces grey colour. • The...

In mice, agouti fur is a dominant trait resulting in individual hairs having a light band of pigment on an otherwise dark hair shaft. A mouse with agouti fur isshown here, along with a mouse with solid color fur, which is the recessive phenotype (A = agouti; a = solid color).A separate gene,which is not linked to the agouti gene, can result in either a dominant black pigment or a recessive brown pigment (B = black; b =brown).A litter of...

Genetic Linkage The six genes listed below are all located on Chromosome 2 of Drosophila melanogaster. Your goal is to construct a genetic map of Chromosome 2. That is, determine the order of these genes along chromosome 2 and the map distance in centimorgans between each gene. To complete this task, you will be given the results of a variety of two-point test crosses involving these genes. For each test cross you may assume that the female is heterozygous and...
