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

Answer:

  • The Island population likely has fewer alleles-that is versions of genes-than the mainland population.

       A- Agree <u>B- Disagree</u>

  • Genetic drift is more pronounced in the island population than in the mainland population in these first few generations

       A- Agree <u>B- Disagree</u>

  • Some harmful traits may have become more common in the island population than in the mainland population

       <u>A- Agree</u>- B- Disagree

  • Biologist observed genetic drift but not evolution

       <u>A- Agree</u> B- Disagree

Explanation:

If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the  population variation that indicate weather selection or other processes occurred.
