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.
Meiosis has two cycles of cell division, conveniently called Meiosis I and Meiosis II. Meiosis I halves the number of chromosomes and is also when crossing over happens. Meiosis II halves the amount of genetic information in each chromosome of each cell. The end result is four daughter cells called haploid cells. Haploid cells only have one set of chromosomes - half the number of chromosomes as the parent cell. Before meiosis I starts, the cell goes through interphase.
