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.
Human sex cells do have 23 chromosomes, but not these 23. None, egg cells don't have chromosomes. No, sex cells do have chromosomes. Meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomesâone homolog of each pair. This is the haploid number.
