Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure cal
nevsk [136]

Answer:

The answer is 46 chromosomes.

Before mitosis, cell duplicates its DNA material so there are 46 chromosomes in duplicates and in total there are 46 x 2 = 92 sister chromatids. During mitosis, sister chromatids first join in the middle of the cell and then separate towards the opposite sides of the cell. After they separate, there are 46 sister chromatids on the one side and 46 sister chromatids on the other side. Each sister chromatid at the end of cytokinesis actually represents the chromosome of the newly formed daughter cell.

vekshin1

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.
