Answer 1:
Cell cycle can be broadly divided into dividing phase and non-dividing or resting phase. Meiosis is a special type of cell division which takes place during gamete formation in the germ cells.
Crossing over means exchange of pieces of chromosomes between homologous chromosomes. Crossing over leads to creation of recombinants or variations. It takes place during Prophase 1 of meiosis, and specifically during pachytene stage of prophase 1.
| Ans 1 |
| Crossing over takes place during prophase 1 (pachytene stage) of meiosis. |
| Ans 2 | Sister chromatids separate completely during anaphase 2 of meiosis. |
| Ans 3 | Envelope forms around each group of chromatids during telophase 2 of meiosis. |
| Ans 4 |
Homologous chromosomes are a pair of chromosome which carry the same set of genes at a given locus, and thus are equal in size and centromere position. One chromosome of the pair is inherited from maternal side and one is inherited from paternal side. |

Meiosis is composed of two chromosomal division called Meiosis I and Meiosis II. Each of the two divisions consists of Prophase, Prometaphase, Metaphase, Anaphase and Telophase and each of these phases is designated I or II according to which division it is a part of. Be sure you know what happens in each phase in regard to the chromosomes, chromatids, spindles and the nuclear envelope. During which phase does synapsis occur and crossing over begin? And in which division, Meiosis I or Meiosis II...
