A chromosomal mutation can occur either during the formation of the egg or sperm, or after fertilization when the zygote is forming. This means the mutation could have occurred in the parent's gametes, or during cell division in the early stages of embryo development.

A normal human baby is born with 10 toes, 5 on each foot. Occasionally a genetic mutation will occur and baby will be born with more or less toes.

Most zygotes with serious chromosomal problems are born with severe mental and physical disabilities; many die before being born or shortly thereafter.
Polydactyly is a type of genetic mutation that results in individuals being born with extra fingers or toes. It is usually an inherited trait, although it can also occur spontaneously. Polydactyly is considered a rare condition.
You do not "get" Down's syndrome. You are born with it. It is a chromosomal condition of the 21st chromosome.
