... the same chromosome would be considered linked because of the fact that inheritance occurs through genetic crosses. Independent assortment deals with the issue of combinations of chromosomes during meiosis, which will be referred to as recombination throughout this report. The aim of this experiment is to figure out whether the Saccharomyces cerevisiae genes his, ade, leu and lys are linked, or if they are on different chromosomes. We can figure this out by calculating the percentage or recombinants versus the percentage of parentals and performing the chi-squared test with the tabulated the results. With this knowledge in hand, a method of genetic mapping, where linked genes were placed in a linear fashion along a chromosome according to their recombination frequency. With the chance of crossing over at any two random points on a chromosome being 50%, the higher the recombination frequency, the more further apart the genes are. This kind ...
