A small island is home to a unique population of land snails. This population was founded by 10 individuals that floated to the island on a log, and it has been isolated from the large mainland poulation ever since. The mainland population consistently had about 10,000 individuals in it through time. The siland population reached 1000 individulas after several generations, and then stayted at this size through time.
A team of researchers compared the genetic variation of the mainland and the isolated island populations for a few generations after colonization. Would biologist agree or dissagree with the following staments?
The Island population likley has fewer alleles-that is versions of genes-than the mainland population.
A- Agree B- Disagree
Genetic drift is more pronounced in the siland population than in the mainlan population in these first few generations
A- Agree B- Disagree
Some harmful traits may have become more common in the island population than in the mainlain poulation
A- Agree- B- Disagree
Biologist observed genetic drift but not evolution
A- Agree B- Disagree

Transposon can cause mutations in genes at or near the site of transposon insertion. it is possible for these elements to transpose away from their original site, causing a reversion of the mutant phenotype. in some cases, however, even more severe phenotypes appear when these elements excise from this site, due to events at or near the mutant allele. what might be happening to the transposon or the nearby gene to create more severe mutations?
