WebIn humans and other mammals, biological sex is determined by a pair of sex chromosomes: XY in males and XX in females. Genes on the X chromosome are said to be X-linked.

WebChromosomes are structures that look like thread, which live in the nucleus (center) of cells. One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus. Without these, our chromosomes would be as tall as we are!
WebThe number of chromosomes for a species is fixed. For example, if a human cell had 44 chromosomes instead of 46, it is anueploidic in nature; nullisomic in fact (2n-2). Just because 44 is an even number doesn't mean it is euploidic! Hope this helped :-) Comment ( 22 votes) Upvote Downvote Flag Show more...
