Your mother donates 23 chromosomes and your father donates 23 giving you 46 chromosomes total. Mutations, such as Trisomy-21, do occur where people can have less or more which usually results in some form of genetic disease.

Humans have 46 chromosomes. Sex cells have 23 chromosomes. Humans can have more or less chromosomes but it results in severe conditions for example down syndrome
is when there are 47 chromosomes (an extra copy of chromosome 21).
