MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The American buffalo has cells containing 60 chromosomes. If one germ cell of a female bison undergoes meiosis, how many chromosomes could be found in the resulting egg?
A
30
B
60
C
120
D
90
Explanation: 

Detailed explanation-1: -If one germ cell if a female bison undergoes meiosis, then thirty (30) chromosomes could be found in the resulting egg. Meiosis is a type of reductional cell division by which a cell produces four daughter cells having half of the genetic material.

Detailed explanation-2: -SOLVED: The American Bison has total of 60 chromosomes.

Detailed explanation-3: -Meiosis is also called reduction division. This type of cell division is involved in formation of gametes. The number of chromosomes is reduced to half at the end of meiosis. So, a cell having 20 chromosomes will give rise to four daughter cells having 10 chromosomes after meiosis.

Detailed explanation-4: -The bison’s sperm cells would have 30 chromosomes because the sperm cells are gametic cells which are haploid cells.

Detailed explanation-5: -Two haploid cells are the end result of the first meiotic division. The cells are haploid because at each pole, there is just one of each pair of the homologous chromosomes. Therefore, only one full set of the chromosomes is present.
