Can you guys please fix this for me.

my project:

Monosomy is the absence of one chromosome from a paired chromosome. For example, Down’s syndrome which has more one chromosome at nubmer21. It makes 47 chromosomes totally. The trisomy reflects the presence of an extra chromosome to the cell. For example, in Turner’s syndrome person has one less X chromosome.

Non-disjunction is failure of cell division when chromosomes separation was occurring. If any chromosome get remains during the separation; means it does not split in two chromatids, it develops into non-disjuction and then non functional or dead cells.

My teachers comments for my project:

Be sure to include all parts of the research assignment.

Compare nondisjunction in meiosis I and II.

Include a more detailed description of one of the listed syndromes.
