Dear John:  Is an egg and a sperm a "cell" or "half of a cell".  Regards, BobC [Sorry for the "shell";-(  ]

[Actually, come to remember it, "half a cell"  is called "haploid", a whole cell is "diploid", could be "triploid" or "tetraploid" if the cell has three or four sets of chromosomes.  Biologists do strange things when rendering Latin and Greek words.]
