Which of the following events is typical of meiosis but not of mitosis?
marin [14]

Answer:

D. the homologous chromosomes are paired AND the spindle is formed

Explanation:

Meiosis is the type of cell division that results in four daughter cells with each having a reduced number of chromosomes (by half). Both meiosis and mitosis occur in different stages including prophase, metaphase, anaphase etc but meiosis occurs in two series of division processes called meiosis I and meiosis II.

In prophase I of meiosis, homologous chromosomes, which are similar but non-identical chromosomes from male and female parents pair to form tetrad or bivalent. This pairing of homologous chromosome is unique and peculiar to MEIOSIS but never mitosis.
