The Egg Cell and the Sperm Get a DowryFrequently in embryo development cells that are not used to construct the soma —the body of the new individual—are put aside but remain in stock as primordial germ cells . Such cells are known in nematodes, insects, and vertebrates.doi:10.1007/978-1-4612-2248-4_5Werner A. MüllerSpringer New...

The head.This part of the sperm carries 23 chromosomes, which contain all the genetic information that the male will pass on. Fertilization occurs when a sperm cell penetrates an egg and combines with the 23 chromosomes the egg contains. That forms a single cell of 46chromosomes. If all goes...
