Table 1 illustrates some of the basic differences between meiosis and mitosis.
Table 1: DIFFERENCES BETWEEN MITOSIS AND MEIOSIS
|1.||It occurs in the division of somatic or body cells.||It occurs in gamete cells.|
|2.||Mitosis does not introduce variation in the genetic makeup of an organism.||Meiosis introduces variation in the genetic makeup of an organism.|
|3.||It starts with the zygote after fertilization and continues throughout the life of the organism.||It occurs only after the age of maturity especially during the formation of gamete cells.|
|4.||No crossing over occurs during mitosis.||Crossing over occurs during meiosis.|
|5.||Chiasmata is not formed during mitosis.||Chiasmata is formed during meiosis.|
|6.||During mitosis, there is no association of homologous chromosomes.||During meiosis, homologous chromosomes associate.|
|7.||In mitosis, two daughter cells are usually formed in one cycle.||In meiosis, four daughter cells are formed in one cycle.|
|8.||One nuclear division and one cytoplasmic division occur per cycle during mitosis.||Two cytoplasmic divisions and two nuclear divisions occur per cycle during meiosis.|
