Final answer:
Each daughter cell will have 20 chromosomes following mitosis of a parent cell with 20 chromosomes, as mitosis creates genetically identical daughter cells with the same chromosome number as the parent.
Step-by-step explanation:
The correct option : c
Mitosis is a cell division process that results in two genetically identical daughter cells with the same number of chromosomes as the original parent cell. During mitosis, the parent cell's chromosomes are duplicated and then distributed equally to the two forming daughter cells. If the starting parent cell has 20 chromosomes, each daughter cell will also end up with 20 chromosomes after cytokinesis completes the division of the cytoplasm. This ensures that the daughter cells maintain the species-specific chromosome number, which is typically diploid for somatic cells. This conservation of chromosome number is crucial for maintaining the genetic integrity and the proper functioning of the daughter cells.
During mitosis, the parent cell undergoes a series of stages to divide its nucleus into two daughter cells. In the process, the chromosomes are replicated and then separated to ensure each daughter cell receives a diploid number of chromosomes. Since the parent cell in this scenario has 20 chromosomes, each daughter cell will also have the same number of chromosomes: 20 chromosomes.
