Why Population of Left-Handed people is less than Right-Handed ones?

Question

i think its about 1/10 .

Answer 1

Some think that handeness forms in the womb. Whichever way the baby is positioned determines with thumb it can suck. It just happens to be more often the right that is favored. It also has something to do with genes because it does run in families. It is not however a case of pure dominent/recessive traits.

Answer 2

It is genetically decided and once you start to discuss genetics  and dominant/recessive genes you will see that it is a simple statistical probability excercise to predict the ratios of left to right handedness.

Answer 3

Probably to do with Genotypes. The genotype for left handedness is recessive, the genotype for right hand is dominant.
