A cell that has 13 chromosomes could: undergo mitosis but not meiosis undergo me

Question

A cell that has 13 chromosomes could: undergo mitosis but not meiosis undergo meiosis but not mitosis undergo either mitosis or meiosis not undergo any kind of division either mitosis or meiosis. If a mother cell has fourteen chromosomes prior to mitosis, how many chromosomes will the daughter cells have? Fifty-six Twenty-eight Fourteen Seven If a mother cells has fourteen chromosomes prior to meiosis, how many chromosomes will the daughter cells have? Fifty-six Twenty-eight Fourteen Seven At metaphase I of meiosis there are: individual chromosomes each consisting of a single chromatid. unpaired chromosomes each consisting of two chromatids. homologous pairs of chromosomes each consisting of two chromatids always an even number of chromosomes each consisting of a single chromatid.

Explanation / Answer

6. d. not undergo any kind of division- either mitosis or meiosis

Trisomy results when chromosomes fail to separate.

Edward Syndrome - Trisomy of chromosome #13

7. c. Fourteen

In mitosis the chromosome number remains the same.

8. d. Seven

In meiosis, the total number of chromosomes is halved in the daughter cells.

9. c. homologus pairs of chromosomes each consisting of two chromatids

The homologue pairs, each with two chromatids line up at the metaphase plate for separation during metaphase I.
