Gerbil parents will care for their young for as long as they are there with them or until another litter arrives. A gerbil pup should wean at four weeks, but it is recommended to keep it with its mother until at least six weeks, if not up to eight. At this point, it is best to separate them into male and female tanks and away from mom and pop, since mom will probably have another litter well on the way and gerbils are sexually mature around 10 weeks of age. If the mother has another litter, which shouldn't be until around 5 weeks of the older litter's lives, see how the mother reacts with them still in the tank, but it most likely will be time to separate them.
They do have seizures (this is common in young gerbils)
Gerbils really don't care about the color of the other gerbils in the tank with them, they really care about personality. For all we know, they could be color blind.
If the human scent gets on the young gerbils too soon when their skin does not have any hair on them, the mothers will kill them because of the different scent.
