Question

Vwhich process occurs when chromosomes do not separate during meiosis?

Answer 1

Answer:

The correct answer is Non-disjunction.

Explanation:

Non- disjunction is the failure of chromosomes to separate during the cell division. This can occur in both meiosis I, II and mitosis during their anaphase.

Non-disjunction of homologous chromosomes lead to "aneuploidy" that is the production of daughter cells with different amount of chromosome number like non-disjunction at meiosis I produce cells with trisomy (one extra chromosome) and monosomy (one less chromosome).

Thus, Non-disjunction is the correct answer.

Answer 2

When chromosomes do not separate during meiosis is called nonjurisdiction.

Sometimes during anaphase, chromosomes will fail to separate properly.
