Hi @charlie98766, a normal helathy child will be born with 23 chromosomes from their dad and 23 from their mum. Some children will however be born with a chromosomal abnormality and have more or less chromosomes than the normal human. In many cases the extra or missing chromosome could be from either parent, so yes you could have fewer chromosomes from you mum. For instance, Downs syndrome children have 3 copies of chromosome 21 – 2 from 1 parent and 1 from another. Lisa.
