Zygote
A zygote is the single cell created when a sperm and an egg fuse. Because the egg and the sperm each carry 23 chromosomes, their fusion results in a zygote with a total of 46 chromosomes, arranged in 23 pairs. Through this process, each parent contributes half of the offspring's genetic information.

A new single-celled organism is formed when a sperm and an egg fuse, with each contributing a set of chromosomes. If an error occurs causing one of the contributing cells to have an extra chromosome, what is the most direct consequence for the newly formed organism?
