Indicate the number of chromosomes and the number of DNA molecules in the prophase of the first and second meiotic cell division. What event occurs with chromosomes in the prophase of the first division?
1) In the prophase of the first division, the number of chromosomes and DNA corresponds to the formula 2n4c.
2) In the prophase of the second division, the formula is n2c, since the cell is haploid.
3) In the prophase of the first division, conjugation and crossing over of homologous chromosomes occurs.
