Explain what would happen if a mistake is made during meiosis

Errors can occur when the chromosomes segregate into the gametes during meiosis resulting in egg or sperm with too many or too few chromosomes. As a result, fertilised eggs and the ensuing embryos may have trisomy (an extra chromosome of a particular pair) in each cell or monosomy (one chromosome fewer in each cell).

the cells dna would be messed up and if the gamiet got fertilized then it could be a deformed baby
