Nondisjunction produces daughter cells with an imbalance of chromosomes. A cell biologist examines the final products of meiosis in a mouse with 24 chromosomes (2n) and finds 2 gamete cells with 13 chromosomes, and 2 gamete cells with 11 chromosomes. Most likely this was because...

If you are studying a diploid organism that has 14 pairs of chromosomes.   How many chromatids will this cell have in the G2 phase   ?   How many chromatids will the gamete of this organism have

If sisiter chromatids of one daughter cell from meiosis l failed to separate during meiosis ll, what would the resulting gametes look like? a. 2 gametes will have 2 of the effected chromosomes, and 2 gametes will have 0 of the effected chromosomes. b. non of the gametes will have any of the effected chromosome. c. 2 gametes will be normal, 1 garmete will have 2 of the effected chromosoms, and 1 gamete will have 0 of the effected chromosome. d. 2 gametes will be normal, and 2 gametes will have 2 of the effected chromosome. e. 2 gametes will be normal, and 2 gametes will have 0 of the effected chormosome

The mosquito, Aedes aegypti, has 3 bivalents (homologous pairs) formed at Meiosis I. How many chromosomes and chromatin strands are present in each of the following stages:

Down's syndrome occurs when either the sperm or the ovum has too many chromosomes. This usually occurs as a result of chromosomes not separating properly in meiosis. Draw what the four reproductive cells would look like if the chromosomes failed to separate in meiosis II. How many of the reproductive cells would be normal?
