Question

If there are 46 chromosomes in a cell, there will be 23 chromatin fibres inside the nucleus during interphase. Is this statement true or not? If not, please make the required change.

Answer 1

During interphase, the chromatin fibres tend to polarize, the number first 23 chromatin fibres are going to be 46 in number. In mitosis the number of chromosomes will always be same (23 pairs or 46 chromosomes in Human) .In meiosis the number of chromosomes will be halved .Half(23 in Human) in male gamete formation (spermatogenesis) and Half (23 in Human) in female gamete formation (Oogenesis). But when the male gamete and female gamete unite,the zygote which later will become Human will always have 46 chromosomes (23 pairs). It is the LAW OF NATURE** Always welcome**
