Humans have a diploid chromosome number of 46. For each of hte mitotic or meiotic phasdes listed below, state the number of chromosomes present and the amount of DNA present in the cell assuming a DNA concentration of 1X in the diploid.

a) telophase of mitosis

b) telophase of meiosis II

C) Metaphase of mitosis

D) Metaphase I of meiosis

Telophase of mitosis:

92 chromosomes,

Telphase of meiosis ll:

46 chromosomes,

Metaphase of mitosis:

46 chromosomes,

Metaphase l of meiosis:

46 chromosomes,

Explanation:

In mitosis, the DNA condenses during the division phase, the teo sister chromatids move apart at the centrioles and form the spindle fibers and the cell divides.

In meiosis one cell gives rise to four daughter cells, each of which has half the number of chromosomes as the parent cell. However meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes.
