INSUFFICIENT LEANING

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that red hair is going extinct because the MC1R alleles that cause it are recessive?

Unclear. Two sources partially address the claim: a Skeptics StackExchange answer explains that recessive red-hair allele frequency stays stable if reproduction rates are equal, and Wikipedia's red hair article states red hair is caused by a recessive allele and is not likely to disappear in the foreseeable future. Neither fully settles whether red hair is going extinct.
