It turns off the ability to produce brown eyes. If the OCA2 gene is completely shut down, then it can cause albinism which makes hair, eyes, and skin, completely melanin-less. ]]> 2022-03-30 18:12:29 UTC https://padlet.com/kmoore4979/p3nt1k8aanbbndcm/wish/2122062348 Why is this an important mutation? ehingstrum4942 https://padlet.com/kmoore4979/p3nt1k8aanbbndcm/wish/2122062990 Its important because the mutation has spread so fast around the population, it's not even considered a mutation and has become very common for others to have blue eyes instead of brown. ]]> 2022-03-30 18:12:52 UTC https://padlet.com/kmoore4979/p3nt1k8aanbbndcm/wish/2122062990 Facts about the mutation ehingstrum4942 https://padlet.com/kmoore4979/p3nt1k8aanbbndcm/wish/2122082577 The mutation is what regulates the OCA2 switch for melanin production and depending on the amount of melanin in the iris, a person can end up with eye colors ranging from brown to green. They found that blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes.
