Sometimes a few individuals are isolated from the rest of the population and can have very different gene frequencies. this is called

The relative frequency of the gene variant expressed as per cent or fraction is called gene frequency. The isolation and the varying gene frequency is due to the Founder's effect.

The loss of the genetic diversity in the new population of the organism that diversified and got isolated from the ancestral population.

This effect depicts the variation in the gene frequencies when the few organisms are isolated from the rest of their population. It can be said as a type of genetic drift in which the allele frequencies of the older population and the new population of the same organism gets differed.

Therefore, the Founder effect is the variation of the gene frequencies in the isolated population.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
