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

Will mark brainliest i only need the ! 1.use ten beads and a centromere of one color to construct the long chromosome. use ten beads and a centromere of a second color to construct the second chromosome in the long pair. make a drawing of the chromosomes in the space below. 2. for the second pair of chromosomes, use only five beads. 3. now model the replication of the chromosomes. make a drawing of your model in the space below. part b: meiosis i during meiosis i, the cell divides into two diploid daughter cells. 4. pair up the chromosomes to form tetrads. use the longer tetrad to model crossing-over. make a drawing of the tetrads in the space below. 5. line up the tetrads across the center of your “cell.” then model what happens to the chromosomes during anaphase i. 6. divide the cell into two daughter cells. use the space below to make a drawing of the result. part c: meiosis ii during meiosis ii, the daughter cells divide again. 7. line up the chromosomes at the center of the first cell, one above the other. separate the chromatids in each chromosome and move them to opposite sides of the cell. 8. repeat step 7 for the second cell. 9. divide each cell into two daughter cells. use the space below to make a drawing of the four haploid cells
