Drosophila Lab Three-point cross Report due Dec. 1/2. Reading: Drosophila: obtain females that are heterozygotes for three different traits. You will then cross the heterozygous females with triple mutant males in a test cross. You will examine the offspring from the test cross to determine the recombination frequencies between the three genes. You will be able to tell if the genes are

Linkage Map Calculating Recombination Frequency And Map

genes are three-point crosses, map distances, and gene order. When three loci are involved, three-point crosses are used to diagram the number of offspring for each phenotype and the frequency of recombination between the two homologous chromosomes (Aggarwal et. al. 2015) . The number of offspring are used to determine the order of the genes by calculating the frequency of parental …

This 3-point mapping project started with a cross between a scarlet eyed, ebony bodied fly and a spineless fly. Use the table below to solve A-C. A) Determine the genotype of the fly being test crossed and the linear order of the genes on the chromosome (which gene is in the middle). B) Calculate the recombination distances between the three loci & draw a map. C) Determine the coefficient of
