What Gene Causes Skin Color?

Does skin color come from Mom or Dad?

The pigment, melanin, passed on to your baby by you, determines skin tone.

In the same way she inherits your hair colour, the amount and type of melanin passed on to your baby is determined by a number of genes (approximately six), with one copy of each inherited from her father and one from her mother.

How do skin color genes work?

Scientists have figured out that several genes are involved in skin color. One of these genes is the melanocortin 1 receptor (MC1R). When MC1R is working well, it has melanocytes convert pheomelanin into eumelanin. Most people with red hair and/or very fair skin have versions of the MC1R gene that don’t work well.

What gene controls skin color?

Scientists have figured out that several genes are involved in skin color. One of these genes is the melanocortin 1 receptor (MC1R). When MC1R is working well, it has melanocytes convert pheomelanin into eumelanin.

Is skin color inherited?

Polygenic Inheritance: Human skin color is a good example of polygenic (multiple gene) inheritance. The “recessive”alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Is skin color a genetic trait?

“Skin color is a classic variable trait in humans, and it’s thought to be adaptive,” Tishkoff said. “Analysis of the genetic basis of variation in skin color sheds light on how adaptive traits evolve, including those that play a role in disease risk.”

What determines a baby’s color?

A couple can have a baby with a skin color that isn’t between their own. It turns out that there isn’t just one or even a few genes involved in skin color. There are hundreds of different stretches of DNA all working together that decide your skin color.
