a lot less than half. Its rumored that natural red heads will go extinct soon.
Scotland has the highest percentage of redheads in the world, with around 13% of the population having red hair. Ireland follows closely behind with around 10% of the population being redheads.
I asked my redheaded blue eyed self that question a couple of days ago. type redhair blue eyes in your serch engine and there are a few sites that will tell you. I would ,but I can't remember.
If brown hair is dominant over red hair, then a person who is heterozygous for brown hair will have a brown hair phenotype. Red-haired offspring with two brown-haired parents are fairly common.
Red hair is clearly the rarest hair color. less than 2% of Total World population. Green eyes are clearly the rarest eye color in total population also less than 2%. So Red hair and green eyes would be the most rare combination of naturally, non-pathogenic occurrences. Light Red hair with Dark Brown eyes is unlikely to occur, Black hair with light grey eyes is unlikely to occur, but BLACK HAIR with GREEN EYES has no record of occurrence {except Mao Lin in the movie, Big trouble in little China}But if your interested the most statistically rare combination would be a female with black hair, albino skin, and heterochromia eyes, one grey and one green. This combination has no record of concurrence and could even be thought of as genetically improbable or virtually impossible. Better question is rarest eye color for Red Hair...or what is the most genetically improbable combination for hair and eye color. There are many reactions for colors occurring when chromosomes and chemicals mix'.
This may cause a lighter red or a darker blonde. actually that isn't true. it depends on which one is the dominant trait. which one is homozygous which one is heterozygous. it all depends.
4% of the Australian population has red hair and 2.5% of the New Zealand population has red hair
Approximately 1-2 of the global population has red hair.
2% of the US population and 4% of the worlds population are red heads
The percentage of men in the population with long hair is relatively low, typically around 5 or less.
Approximately 2 of the global population has naturally blonde hair.
Roughly 10 percent of Irish people have red hair.
yes Answer: Possible experiments: * Microscopic analysis to determine if it looks different from other colours of hair * Cross sectional appearance vs other colours* Tensile strength (how strong is it)* Trace metals examination (what makes it red) * Percentage of red hair in a population * Hereditary of red hair (trace family tree to see if red hair is a recessive or dominant gene)
