Fertilised human egg. Light micrograph of a human egg cell after fertilisation. Inside the egg are two rounded pronuclei,one comes from the egg and one from the sperm. When they fuse,the egg becomes a zygote containing the full 46 human chromosomes. Around the egg is a thick zona pellucida layer; sperm can be seen (left and lower right) embedded in this layer. This egg will soon begin its first cell division. Magnification: x350 when printed at 10 centimetres wide | |
