One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.
yes chromosomes are present when cell divide
46 chromosomes..
Different organisms have different numbers of chromosomes. For example, humans have 23 pairs of chromosomes (46 total) while cows have 30 pairs (60 total) and goldfish have 50-52 pairs (100-104 total).
