Can a group of gray cats become white cats after residing in North Pole 100 thousand years?

Answer 1

They would never survive. I know what you're asking though, and it's a question about natural selection. White fur would have to be a variant that already occurred in this population. The cats could not all breed grey to start with. There would have to be a recessive allele for white that did not show. When two cats that both had the white recessive gene bred they would produce a white cat. A few white cats would crop up at first in your group. And there would have to be a predator which spotted and caught the grey cats more often than the white. White would become the predominant color, then the only color after a while. This is an illustration of natural selection, survival of the fittest, and it's a mechanism of evolution.

Answer 2

Can they - yes. The descendents of a group of gray cats can become white cats after living in New York City for 7 years. It is not likely, but it is possible.

Being at the north pole would make it less likely, since the cats would not survive to reproduce. The cold would kill them.

Once you assume that they do survive you eliminate natural selection which makes the basic theory of evolution pointless.

Answer 3

Somewhere in that gene pool there would have had to have been a recessive gene for white. After years of multiplying, that gene would come out more predominantly. Then, the gray cats would no longer have a higher survival rate since the white cats would blend in better. Eventually, the gray cats would become the minority, possibly even extinct, and the white cats would predominate.

Answer 4

you WOULD NOT need a mutation. Coloration for cats is controlled by multiple chromosomes and so a population of gray cats contains all the genes necessary to produce a white offspringe already. the only way the population will tend to be entirely white is if some selective condition exists which would make it disadvantagious to be gray or advantagious to be white. for example, a predator that can spot gray cats, allowing the lighter hued cats to survive more effectively. as such, the population drift would tend towards lighter colored fur and the population would become white fairly quickly. This would most likely (depending on the density of population and the threat from the predator/situation) occur MUCH more rapidly than in 100 thousand years as well. the industrialization and subsequent environmental reaction showed a shift of moths coloration from white to dark and back to white again in a period of less than one hundred years. white moths could not longer hide on birch bark due to polution during industrialization, so the dark moths outbread. when the environmental concerns kicked in and factories had to clean up, the bark of the trees became clean white again, and the dark moths could easily be seen by predators. the population shifted back to light colored moths which could survive long enough to reproduce.

Answer 5

If white cats survive better there (e.g. less likely to become a polar bear's dinner) then there would definitely be a selection advantage for white cats. So, if there are white genes in the genome (or some arise by variation), and these get expressed, you are likely to get white cats.

Answer 6

Assuming you mean their descendants would evolve into white cats, yes, I think it is possible. I don't know if that's what would happen, but it is possible, as long as the cats managed to survive long enough for that to happen.

Answer 7

They could become white in less than a year jest the genes of the parents would have that trait and it could surface at any time after breeding

Answer 8

after 100000 years, you would probably have several different colored cats. I'm sure they'd have several thousand white cats by then.

Answer 9

yes through micro evolution this should happen bc the trait of white is the best to survive.

Answer 10

No u dumb ***!!!! Thats like saing if e humans were to live with horses 4 a hundred years they would turn into 1!!!
