Why does meiosis result in more genetic variation than mitosis?
It would be wrong to consider mitosis insignificant as it helps in cell repair and replacement in our daily life and it would be impossible to survive without it and asexual reproduction as well but if it weren't for meiosis, none of us would have been born :) Meiosis is responsible for the division for our gamete cells which leads to the formation a zygote. from there on mitosis takes over.
Does random alignment of chromosomes during Meiosis produce genetic variations?
In meiosis crossing over may occur at certain points on a chromatid. Crossing over is where variation occurs in allele combination. When a Zygote is formed alleles from mother and father cross over.. this is why you may have some features resembling your father and your mother... or grandma or grandpa... etc... There can be mutations ( messups ) in mitosis but the actual process results in no genetic variation. AP bio
What is copied before mitosis begins?
DNA, the genetic material, of course. Also mitochondria and chloroplasts need to divide. This is the process of mitosis where two daughter cells are produced and both will need the complete complement of genetic material; DNA.
The process of what produces a new copy of an organism's genetic information?
The process that makes a new copy of an organism's genetic information and then passes it on to new cells is called mitosis.
How does variation occur?
Variation or mutation occurs within the DNA. It is a natural result of the replication process, or the copying of one DNA strand to make new DNA during reproduction. If the new mutation ends up making some kind of variation that does not kill the organism, then the variation will be passed on to new generations. This is how new traits are formed. When the variation is actually more useful than a trait that the organism's parents had, that new variation will be passed along as a survival trait.
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.
Why are mitosis and mitosis similar?
Because they both result in the formantion of gametes; however there is no genetic variation in meiosis.
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
How is genetics influenced by the processes of mitosis and meiosis?
Genetics is influenced by the processes of mitosis and meiosis because they are responsible for the replication and division of cells, which ultimately leads to the transmission of genetic information from one generation to the next. Mitosis produces two identical daughter cells with the same genetic information as the parent cell, while meiosis produces four genetically unique daughter cells through a process of genetic recombination and segregation. This genetic diversity is essential for the variation and evolution of species.
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.
What is meiosis about?
Meiosis is Sexual Reproduction, unlike Mitosis, that is responsible for cell growth and other functions. Meiosis has the same phases as Mitosis except that it undergoes those phase twice (Meiosis l and ll). This results in 4 daughter cells, unlike Mitosis which results in only 2 daughter cells. Also, in Mitosis the daughter cells are identical to the original cell, while in Meiosis, it increases genetic variation, because it has characteristics of both parent cells.
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.
What specific meiotic events contribute to meiosis leads to significant genetic variation while mitosis does not?
may be its genetical diffence
How does the process of meiosis differ from mitosis in terms of genetic variation and cell division?
In meiosis, cells divide twice to produce four genetically unique cells with half the number of chromosomes, leading to increased genetic variation. In contrast, mitosis results in two identical cells with the same number of chromosomes as the original cell.
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.
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.
Why meiosis 2 is similar to mitosis?
Because they both result in the formantion of gametes; however there is no genetic variation in meiosis.
