Question

A cell that contains 12 chromosomes divides meiotically to produce a total of daughter cells, each containing chromosomes. Identify the stage of the cell cycle or the stage of meiosis described. a. genetic information replicated b. centromeres separate and the chromosomes move toward the poles crossing over occurs homologous chromosomes pair homologous pairs of chromosomes separate to opposite poles Draw the arrangement of chromosomes at metaphase in a cell where 2N = 6. Do this for mitosis, meiosis I, and meiosis II.

Explanation / Answer

Answer 1)

         A cell that contains 12 chromosomes divides meiotically to produce a total of 4 daughter cells, each containing 6 chromosomes.

Explanation: Human contains 46 chromosomes (2n) in all somatic cells but in germ cells (sperm in male and egg in females) only 23 chromosomes (n). In this meiosis takes place to produce four daughter cells in one cycle. Meiosis is also known as reduction division.

Answer 2)

a) Genetic information replicated. -   At the onset of meiosis

d) Pairing of homologous chromosomes.- At the onset of meiosis

c) Crossing over occurs. At the onset of meiosis

e) Homologous pairs of chromosomes separate to opposite poles.- At the onset of meiosis

b) Centromeres separate and the chromosomes move toward the poles.
