| Drosophila somatic cells contain 8 chromosomes. What is the number of chromosomes and DNA molecules contained in cells in Meiosis I and II Prophase?
Before meiosis, the interphase process takes place in the cell – a preparatory stage for division. In this case, there is a doubling of the amount of DNA in the chromosomes of the cell nucleus. Meiosis – cell division with a decrease in the number of chromosomes and DNA molecules in them. Moreover, in the prophase of meose 1 and meose 2, the chromosomes always remain dichromatid. Then the fly has a Drosophila:
prophase of meiosis 1 – 8 chromosomes, and DNA molecules – 16;
prophase of meiosis 2 – 4 chromosomes and 8 DNA molecules.
