Explain separation of homologous chromosomes, Biology

Assignment Help:

Q. What are the respective functions of the separation of homologous chromosomes and of the separation of alike chromatids in meiosis?

The separation of homologous chromosomes in meiosis I has two major functions to reduce to a half the total number of chromosomes, generating haploid daughter cells at the end of the process, and to make possible genetic recombination since the separation is aleatory that is each pair of daughter cells can be different from the other pair relating chromosomal combination from paternal and maternal origins and if crossing over is considered each of the four resulting cells can be different from the others.

The separation of identical chromatids in meiosis II has the same function it has in mitosis to separate the chromosomes earlier duplicated to the daughter cells.
