(This is review from last chapter.). The addition and multiplication rules. (You will get more practice using these later.). If PD NPD, then the two genes are linked. When PD NPD, the haploid spores of theparental class significantly outnumber the haploids of the recombinant class, a sign of linkage.Consider and exam Part 3. Location of genes. Meiosis. Linkage and mapping. A map of the human Y chromosome. 2. Location of genes. One of the things Mendel didn’t solve was exactly where genes are located in cells.

These phenomena observed in Saccharomyces cerevisiae are highly conserved in eukaryotes, thus rendering yeast, which is easy to use, an essential model organism.
