The processes that occur in meiosis but do not occur in mitosis are:
- Separation of homologous chromosomes.
Mitosis consists of the division of an original cell to form two genetically identical daughter cells.
Meiosis, on the other hand, is a required process in preparation for sexual reproduction, and unlike mitosis, it allows high genetic recombination.
That is, in meiosis I the prophase is very long and in its course the homologous chromosomes (identical because one comes from each parent) pair and recombine to exchange genetic material.
Mitosis creates two daughter cells both diploid and identical, meiosis, on the other hand, produces four descendant cells, but all haploid.
In the anaphase I of the meoisis the homologous chromosomes of each bivalent (each one formed by two sister chromatids) separate from each other, tend to one pole of the cell and form two haploid poles (n).
Therefore, we can conclude that the processes that occur in meiosis but do not occur in mitosis are: Separation of homologous chromosomes and recombination.
