Question

Consider the abbreviated model of meiosis. The end result of meiosis should be the production of four haploid gametes. In this example, an error has taken place. Describe and name this error. A) Nondisjunction of sister chromatids during meiosis II. Sister chromatids fail to separate. B) Translocation of sister chromatids during meiosis II. One chromatid is translocated into incorrect cell. C) Separation mutation during meiosis I. Resulting gametes in meiosis II have incorrect chromosome number at end of meiosis. D) Replication error during meiosis I. Results of mutation show during meiosis II as incorrect chromosome number in two gametes. Elim

Answer 1

Answer:

Answer number A

nondisjunction of sister chromatids fali to separate

Answer 2

Non disjunction of chromatids

Step by step explanation:

• The answer for given question is A) Nondisjunction of sister chromatids during meiosis II.

• There are two different types of cell division: Meiosis and Mitosis.
• Meiosis is a cell division in which a parent cell divides twice to produce four daughter cells containing half the number of chromosomes from the parent cell. The cells which undergo meiosis are sperms in male and eggs in female.
• Sometimes during the process of meiosis chromosomes fails to separate from the parent cell between any of the stages of the meiosis (meiosis I or meiosis II)  this leads to either less number of chromosomes or more number of chromosomes in progeny
