Bewildering Bs: an impression of the 1st B-Chromosome
... Another intriguing point that was raised is why are there so few organisms with many different types of Bs? This does not seem to result solely from a lack of study. From a selective point of view, it may be that there is a narrow niche for a B to exist in a species and hence strong selection for a ...

MEIOSIS
... Meiosis scrambles the specific forms of each gene that each sex cell (egg or sperm) receives. This makes for a lot of genetic diversity. This trick is accomplished through independent assortment and crossingover. ...
