Answer
The gene is incomplete recessive and redheads are a small minority of the human population so yes, if they breed freely with people with different hair colors eventually they'll disappear. Some people will still carry the gene but they'll have auburn hair or strawberry blonde hair, not red hair.

What color was Tyrannasaurus Rex? Why did they go extinct?

Answer
>>>>>What color was Tyrannasaurus Rex?
We have no absolutely no way of knowing. It almost certainly varied with the age of the animal.
The young animals almost certainly had feathers, and given their small size it seems reasonably that both the feathers and the skin would have been dark brown or black to enable them to heat from sunlight. The addittion of spots or stripes would add in hiding. The young of most large birds and mammals today are stipe dor spotted so it seems reasonable to assume the same for tyrranosaur chicks.
The adults seem to have lacked feathers, at least for the most part. In that respect they seem to be like elephants rhinos, whales and other large mammals where the young retain at leat sparse hair that is almost totally absent from the adult.
What colour the adults were we simply canât know. Animals of that size generally have little use for camouflage colouration so they can be whatever colour they like. The big question is how much of a role vision played in courtship. If tyrannosaurs were like modern birds we would expect the males at least to have extremely brightly coloured heads at the very least.
So an olive grey Tyrrannosaur with a bright blue head and big red circles under the eyes is no less likely than any other colour scheme.

They most certainly were NOT large versions of the lizards we have today. They are only very distantly related to modern lizards. The closest living relatives are, not surprisingly, birds.
We arenât entirely certain what the lifestyle of a T. rex was, they seem to have been a combination of predator and scavenger. In terms of lifestyle the closest living comparison would probably be a lion or hyaena.
They were in no way lizard-like.
>>>>They went extinct because of a meteor
That is one theory, but one that is rapidly losing credibility. There were probably multiple factors leading to the mass extinction that took T. rex along with numerous other species. A comet or meteor impact just doesnât explain all the observations
