probably true for a lot of people on here lol ;-)

Left-handedness is a recessive trait. Right-handed people can be homozygous, (RR) or heterozygous, (Rr) to be left handed you must be homozygous, (rr). To work out what chances your child would have hypothetically of being left-handed, you can work it out on a punnett square. eg., if both parents were homozygous right-handed, the offspring would be 100% right handed. If there was one homozygous right-handed parent and one heterozygous parent, the offspring would be also 100% right handed, but may be either hetero or homozygous right-handed. If both parents were heterozygous the child would have 25% chance of being left-handed (homozygous-rr), 50% heterozygous right-handed and 25% chance of being homozygous right-handed. And finally, if both parents were left-handed, the child would have 100% chance of being left-handed

I bet most are right handed wives =p
