10, because it's easier to detect the ratio of 10 than the ratio of 100
On the population of 10 individuals
When there is low genetic variation in a population the species produced are unlikely to withstand diseases.

genetic variation = crossing over. you get the chance to mix genes. it would be cloning if they didn't cross over. meiosis - crossing over mitosis - cloning
A widespread disaster would reduce the variety within the human genetic pool by eliminating all but certain segments of the population. A global plague could potentially have the greatest effect, as plagues (see: black plague, Spanish influenza) often will often decimate all of a local population save for those with genetic immunity--thus standardizing that mutation in future populations. Global catastrophe could also inhibit travel, and would limit human reproduction to their immediate region, limiting the genetic range of potential offspring.
One problem is that the population will loose it genetic variation. With little genetic variation a population is less likely to have some individuals that will be able to adapt to a changing environment.

The population will have more possible adaptations. a[ex just gave me the answer
Which would most likely decrease the genetic variation in the human population?

Genetic Drift
1) No mutations 2) No natural selection 3) No individuals in or out of a population. 4) Large population 5) Random mating It is, however, impossible for a population to achieve genetic equilibrium. There are always going to be mutations occurring from time to time.
Genetic diversity would increase the survival of the rat population because they would be more capable as a species of surviving in different environments.
If I'm not mistaken genetic drift is the random change in the genome of a population over time. This being said it would be possible that this random changing could eventually remove certain diversity from a population.
because genetic modifications have more allieles than the first and second generation youre welcome:)
A gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Thus the actively interbreeding population of a species is a genetic pool comprising the genes for that species. Should something happen that would separate the breeding population into two populations where the populations could not longer mingle to interbreed, there would now be two genetic pools.
There are about 500 Siberian tigers currently surviving in the wild, but the effective population accounts for genetic diversity. BBC says that the tiger has a very low diversity, which means that any disease or rare genetic disorders will probably be passed on to the next generation. A more diverse genetic population would increase its chance of survival and would be able to "cancel out" diseases and disorders with healthy genes.
