Which of the following events is typical of meiosis but not of mitosis? A the chromosomes are highlighted
B. the centrioles are formed
C chromatids separate
D. the homologous chromosomes are paired AND the spindle is formed

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.

Variation because if there aren’t different types, then it can’t occur
Overpopulation because then there can not be variation in the offspring
Adaptation because then some of the species have to adapt to the environment so the best traits can be chosen
And descent with modification, so the best types can survive
