Redheads are More Likely to be Left-Handed
On average, around 15% of the population is left-handed, and as it’s a recessive gene, that proportion is unlikely to increase. What’s interesting is that red hair is also a recessive gene, and people with red hair are also more likely to be left-handed. This is an excellent example of how recessive genes slowly disappear over time, except in certain pockets of the gene pool.
