In this video we learn about the distinct differences of egg and sperm cells, which are also known as gametes. We will see how the chromosomes from each cells come together to form our unique genetic code. The gametes (sperm and egg cells) are haploid – so only have half the number of chromosomes. This is 23 in humans. When a sperm fertilises an egg cell, the chromosome number becomes diploid – so the normal number of chromosomes which is 46 in humans (found in 23 pairs). One chromosome in each pair comes from the mother and the other from the father. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.
