Question

Which best explains how binary fission contributes to the genetic continuity of a population? A Binary fission maintains genetic continuity because the daughter cells contain twice as many chromosomes as the parent cell. B Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell. C Binary fission does not maintain genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell. D Binary fission does not maintain genetic continuity because the daughter cells contain a smaller number of chromosomes than the parent cell.

Answer 1

Answer:

B Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.

Explanation:

Genetic continuity ensures that genetic information is passed from one generation to another in correct way so that the resultant progeny has the complete set of genes required for survival. For example, at the end of mitosis, daughter cells should have the same number of chromosomes as parent cell.

Binary fission is a method of reproduction in some organisms like bacteria. It is an asexual mode of reproduction in which the parent cell splits into daughter cells without the process of fusion with another cell. It still maintains genetic continuity because the daughter cells are identical to the parent cell and thus have same number of chromosomes and type of genes.
