It's a frequently-measured fact, called "founder effect." But they don't "lose" genetic information, they have less genetic information because they have fewer individuals. Over time, genetic information will increase, if the population becomes established.
There are many, many transitional forms. Even honest YE creationists admit this.
Almost always it is. That's what we see in nature. This wasn't first noticed by Eldridge and Gould; Ernst Mayr noticed that aberrant populations tended to be found in isolated places. Eldridge and Gould explained why. Founder effect is well-documented, as is allopatric speciation.
You've been misled about that. The evidence has accumulated to show that allopatric speciation is the common mode. The fossil record rather clearly shows the usual pattern of speciation to be quite rapid, followed by long periods of stasis. As Darwin noted, a well-fitted population in a constant environment shouldn't change much, because of natural selection.
It's the usual mode, but not always. Horses, ammonites and some others show more gradual change.

But then it’s not an isolated population

so once again, the PE theory of Gould, is disproven by actual science by wildlife biology

it requires isolated populations.
