How does the process of mitosis differ from meiosis in terms of genetic variation and the number of cell divisions?
In mitosis, one cell divides into two identical cells, resulting in no genetic variation. There is only one cell division in mitosis. In meiosis, one cell divides into four cells, each with different genetic material, leading to genetic variation. Meiosis involves two cell divisions.
Differences between mitosis and meiosis?
place of occurence ;mitosis= somatic cells | meiosis=gonadic cells crossing over;mitosis=does not occur | meiosis=occur during prophase of meiosis 1 to form tetrads number of daughter cell;mitosis=two | meiosis= four genetic variation;mitosis=no variation produced| meiosis=produces genetic variation genetic composition in daughter cell; mitosis=identical to the parent cell | meiosis= non identical to the parent cell and each other
What term should not be confused with Mitosis?
Meiosis should not be confused with Mitosis. Mitosis is a type of cell division that results in two identical daughter cells, while meiosis is a type of cell division that results in four haploid daughter cells with genetic variation.
What are the key differences between meiosis and mitosis in terms of their processes and outcomes, and how do these differences impact the genetic variation and cell division in organisms?
Meiosis and mitosis are both processes of cell division, but they have key differences. In meiosis, there are two rounds of division resulting in four daughter cells with half the number of chromosomes as the parent cell. This leads to genetic variation as the daughter cells are genetically different from each other and the parent cell. In contrast, mitosis results in two identical daughter cells with the same number of chromosomes as the parent cell. This lack of genetic variation is important for growth and repair in organisms.
How does the process of mitosis contribute to genetic variation through the phenomenon of crossing over?
During the process of mitosis, genetic variation is not directly contributed through crossing over. Crossing over occurs during meiosis, not mitosis. In crossing over, homologous chromosomes exchange genetic material, leading to genetic variation in offspring. Mitosis, on the other hand, is a cell division process that produces genetically identical daughter cells.

Which cell division mitosis or meiosis has genetic variation and are not just identical cells?
Meiosis. Genetic variation is achieved by the random division of the chromosomes between the two daughter cells, and further recombination of specific genes between paired chromosomes before the division.
Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for genetic variation

Why are mitosis and mitosis similar?
Because they both result in the formantion of gametes; however there is no genetic variation in meiosis.

How does the process of mitosis differ from meiosis in terms of genetic variation and cell division?
In mitosis, a cell divides into two identical daughter cells, maintaining the same genetic information. This process is used for growth and repair. In contrast, meiosis involves two rounds of cell division to produce four daughter cells with half the genetic information of the parent cell. This creates genetic variation through the shuffling of genetic material during crossing over and independent assortment. Meiosis is used for sexual reproduction to generate offspring with unique genetic combinations.
Why must there be two types of cell division?
There are two types of cell division, mitosis and meiosis, to serve different purposes in organisms. Mitosis is responsible for growth, repair, and asexual reproduction by producing identical daughter cells. Meiosis, on the other hand, is essential for sexual reproduction, generating genetically diverse gametes for offspring with genetic variation.
Where do you expect genetic differences between cells to arise from mitosis or from meiosis?
That is a good question. In mitosis, you don't get regular genetic variation but chance mutations can occur. In meiosis with fertilization, you get pairing of DNA from different hosts on a regular basis. I would choose the latter.
What type of cell division Mitosis or meiosis is important in genetic study?
Both
