Which THREE statements describe how the models of mitosis and meiosis demonstrate genetic continuity?


Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.


In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.


In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.


In Metaphase (Metaphase II of meiosis) the chromosomes are lined up properly, indicating that the chromatids will separate evenly and provide the daughter cells with equal amounts of genetic material.


In Telophase (Telophase II of meiosis) the amount of chromatin present is equal to the amount present during Interphase, indicating that the daughter cells will receive the same amount of genetic material as the parent cell.

The three statements that describes how the models of mitosis and meiosis demonstrate genetic continuity are listed and explain below.

In Anaphase, chromosomes line up in the middle of the cell while the spindle fibres pulls them apart.

Therefore the statement below about anaphase is correct.

  • Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.

In interphase, the synthesis of DNA occurs where the chromosomes replicates forming two identical copies of DNA.

That is, the cell now has 92 chromosomes which is enough DNA for two cells.

Therefore the statement below about interphase is correct.

  • In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.

In the prophase, the mitotic apparatus appears; this consists of two centrioles separated by the mitotic spindle which is formed from microtubules.

The formation of these mitotic spindle fibres indicates that the chromosomes will be split evenly.

Therefore the statement below about prophase is correct.

  • In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.
