Risk indexes. Definition: Categories of risk used to calculate fundamental beta, including (1) market variability, (2) earnings variability, (3) low valuation, (4) immaturity and smallness, (5) growth orientation, and (6) financial risk.
(See figure below, where meiosis I begins with a diploid (2 n = 4) cell and ends with two haploid (n = 2) cells.) In humans (2 n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). Prophase I.
In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.
