Question

If a nondisjuction event occurs during meiosis 1, how many daughter cells of the original parent cell that underwent meiosis will bem issing a chromosome?

Answer 1

Answer:

The correct answer will be- two daughter cells

Explanation:

Non-disjunction is the process which leads to the formation of daughter cells with an abnormal number of chromosomes during meiosis.  The non-disjunction occurs due to the failure of the separation of the homologous chromosomes during anaphase I or anaphase II.  

If meiosis takes place during anaphase I of meiosis I and completes meiosis II then it will result in the formation of the two daughter cells with on extra copy of the chromosome while two cells with one copy of the chromosomes which result in a formation of monosomic cells.

Thus, two daughter cells are the correct answer.
