THE PROCESS WHICH ENSURES THAT THE CHROMOSOME NUMBER FOR EACH SPECIES OF ORGANISM REMAINS CONSTANT FROM GENERATION TO GENERATION IS CALLED

• A. fission
• B. fusion
• C. meiosis
• D. mitosis ✓
• E. oogenesis

The answer to the question is: D. mitosis

In the context of genetics and biology, the process that ensures the chromosome number for each species of organism remains constant from generation to generation is termed mitosis.

Mitosis is a fundamental process in which a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell. This process is crucial for growth, repair, and asexual reproduction in organisms. During mitosis, the chromosomes are replicated and then segregated equally into the daughter cells, ensuring that each cell receives a complete set of chromosomes.

On the other hand, meiosis is another type of cell division that occurs in sexually reproducing organisms. Meiosis involves two rounds of cell division and results in the formation of gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. This reduction in chromosome number is essential for sexual reproduction and genetic diversity.

While mitosis maintains the chromosome number in somatic cells (body cells), meiosis ensures the production of haploid gametes with half the chromosome number. Therefore, when it comes to maintaining the chromosome number for each species of organism from generation to generation, mitosis plays a crucial role in preserving the diploid chromosome number in somatic cells.

In summary, mitosis is the specific process that ensures the chromosome number for each species of organism remains constant from generation to generation in somatic cells.
