Genetic Recombination

Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.

Microbial Genetics

Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.

We have discussed meiosis in yeast. One ascus e one melotic event. Two haploid yeast strains are crossed together, one wild type, the other mutant for 2 linked genes. The resulting diploid strain undergoes melosis eventually (=many meiotic events > many asci). A. What will the results be if the 2 genes are very far away from each other (certainly more than 50 map units)? B. What will the results be if the two genes are right next to each other, "no distance at all, zero distance"? (Explain your answers). Results here are patterns of asci and their percentages. Like for example "50% tetratypes, 0% ditypes", etc. If you forgot what a ditype or a tetratype is, you can illustrate them like that.

Although the white colonies are roughly the samesize, the red sectors within some of the whitecolonies vary markedly in size. Why? Do youexpect the majority of the red sectors to be relativelylarge or relatively small?
