The separation of homologous chromosomes is called:

A. synapsis.
B. segregation.
C. mitosis.
D. fertilization.

im confused between B n C

See if this fits the definition of mitosis.

The is a poorly worded question which would confuse me, but I want to add my two cents if that is worth anything. Mitosis is the process where cells divide and includes the doubling of chromosomal material, segregation, and the division of the cell to produce two identical cells. Therefore, the best answer choice to your first question is B.

The separation of homologous chromosomes is called segregation.

The separation of homologous chromosomes is actually called segregation.

To understand why, let's break down each option and see if it fits the process:
- A. Synapsis: Synapsis is the process by which homologous chromosomes pair up during meiosis, not the separation.
- B. Segregation: This is the correct option. Segregation refers to the separate distribution of homologous chromosomes into different cells during meiosis.
- C. Mitosis: Mitosis is a different process altogether, where a cell divides into two identical daughter cells containing the same number of chromosomes. It does not involve the separation of homologous chromosomes.
- D. Fertilization: Fertilization is the fusion of gametes (sperm and egg) to form a zygote, which is not directly related to the separation of homologous chromosomes.

Therefore, the correct answer is B. segregation.
