Your Assignment You will be setting up several fly crosses, comparing offspring ratios, and determining the mode of inheritance of those genes. We will be using mutants in the white gene and in the miniature gene for this lab. The white gene and the miniature gene are both located on the X chromosome. Follow the […]

Using the table of critical values shown-what is the P-value range we would obtain for our test?
When two heterozygotes are mated, the ratios of the offspring produced should be in a 1:2:1 ratio if normal Mendelian segregation is occurring. If one of the alleles is dominant, then the phenotypes observed should be present in a 3:1 ratio with the dominant phenotype more common than the recessive one. We can use an […]
What might be the mode of inheritance for the affected (shaded) individuals?
Pedigree and non-Mendelian practice problems Only individuals with the affected phenotype are shown in the pedigree below, no other individuals are indicated. What might be the mode of inheritance for the affected (shaded) individuals? Be sure to explain what evidence in the chart supports your conclusion? Use the roman numerals that indicate generation and the […]
