Nimitz class aircraft carrier design. The more recent Nimitz Class carriers (CVN72-CVN76) have a displacement of 102,000t when fully loaded. They have a length of 317m and beam of 40.8m.
Each of these daughter cells has to contain 23 chromosomes, half of the original 46. Again these steps must occur in this exact order or the resulting cells will have an incorrect number of chromosomes.  It has probably become obvious at this point that mitosis and meiosis are not simple processes.
Chromosome changes may be inherited from a parent. More commonly, chromosome changes happen either when the egg or sperm cells are made, or around the time of conception. These changes occur without us being able to control them. There are two main types of chromosome changes that can occur.
