Document Summary

Objective is to map the specific location of a gene that codes for a specific trait on a chromosome. Creating a new combination of alleles between generation to generation. One chromosome carrying all recessive and one carrying all dominant. How often we see a recombination of a and b that allows us to determine the distance between a and b. The further apart genes are, the more likely they are to undergo recombination. More likely to have a recombination of a and e than a and. The observation that 2 traits assort independently from one another. Always a recombination event between the 2 genes. Pr/pr vg/vg x pr/pr vg/vg = pr/pr pr/vg (purple eye color and vestigial wings) pr/pr vg/vg x pr/pr vg/vg = pr/pr vg/vg. Linkage between the gene that affects eyes to the gene that affects wings. The vestigial (vg) and purple (pr) genes are on the same pair of homologous chromosomes.
