The Founder Effect refers to a fascinating phenomenon whereby a small group of individuals establishes a new population. This leads to a decrease in genetic variation and an increased prevalence of certain genetic traits among the descendants. A Stumbling Block for Genetic Diversity1. Since more offspring are produced than an environment can support, organisms within a population must compete for resources to survive. 2. Due to variations within the population, some competitors will be better equipped for survival than others. 3. The best-equipped organisms will survive and will produce well-equipped offspring.

I observed about the genetic variation between the parent and founding populations that there is a 75% chance of a bead or allele being in the mix. The chances of a bead or allele being in the mix is 75%. This is because the founding population is a subset of the parent population, and thus contains a smaller amount of genetic variation.A 22-year-old captured the longest documented Burmese python ever caught in Florida.
