What is the exchange of genetic material between nonsister chromatids called? 12. During what phase does crossing-over occur? 13. During what phase do homologues separate? 14. If a parent cell has 48 chromosomes, how many does each daughter cell have at the hat term describes the pairing of chromosomes during prophase 1? separate: during anaphase II -separate end of meiosis II?

Explanation / Answer

Ans5) The DNA replication takes place in the S phase or the synthesis phase of the cell cycle in mitosis.

Ans 7) Parents cells are called diploid (2n) and daughter cells are called haploid (n).

Ans 11) The genetic exchange between the non-sister chromatids is called synapsis.

Ans 9) Synapsis is the term used for the pairing of the chromosome in prophase 1.

ans 12) Crosssing over takes place between prophase 1 and metaphase 1.

Ans 13) Homologous chromosome separate during anaphase of meiosis 1.
