do you mean milotic? and there is no suck thing as a meiotic.

∙ 10y agoIf there had been only meiosis and not mitosis then life wouldn't have survived very long. With successive halvings of genetic material there would be nothing left after a few generations, unless there were a way to constanlty add new DNA at each generation. If this happended there would probably be no such thing as a species, since there wouldn't be groups of lifeforms that are genetically close enough to be considered a species. Gaining half as much random DNA would be an extremely high rate of mutation, and it could be wasteful as far as selection of the fittest traits is concerned, if only half is what was selected and the other half completely random.

∙ 9y agoEven the simplest life forms reproduce by duplicating DNA. Whether the difference between the processes of budding and mitosis are determined to be sufficiently different to make budding the primary form of reproduction in a world where mitosis and meiosis never evolved is essentially like saying that evolution stopped, since budding was the precursor to mitosis. Certainly, single-celled animals have 'learned' to exchange genetic material so there would be an increase in genetic variation in the very different world proposed here. Unfortunately, the result of a dead end scenario such as this would not bode well for complex multicelluar life forms. Or, perhaps this assessment lacks a very good imagination.

The second meiotic division is essentially a mitotic division except for the fact that the cells produced are?
Haploid
What are two types of eukaryotic cell division?
Meiotic and Mitotic [ Meiosis and Mitosis ] are the two Types.
What is the primary functional differences between mitotic anaphase and meiotic anaphase II?
functionally they are pretty much the same. overall the number of chromosomes is different.
Is Down syndrome more severe in mitotic nondisjunction or meiotic nondisjunction?
It's more sever in meiotic nondisjunction, since this is the most common way that trisomy 21 (Down syndrome) arises. mitotic nondisjunction is less sever because it means that some cells will be mosaic, meaning they could be normal while some with have the (2n+1) while other cell will be (2n). So, in mitotic nondisjunction it depend how many cells are carrying the extra 21 chromosome. In end of the day they can't be worse than Down syndrome that rose from meiotic nondisjucntion since it has the highest amount of cells carrying trisomy 21.. I hope this helps
In what process does cell division produce germ cells?
So far as nuclear division is concerned, in somatic cells it is mitotic whereas in germ cells it is meiotic.
How would you distinguish human mitotic cells from human meiotic cells?
By counting the number of daughter cells resulting from mitotic and meiotic division
What will happen if mitotic and meiotic processes never evolve?
do you mean milotic? and there is no suck thing as a meiotic.
Cells that undergo mitotic division but not meiotic division are called?
somatic cells
The second meiotic division is essentially a mitotic division except for the fact that the cells produced are?
Haploid
What is a an enzyme that drives both the mitotic and meiotic cycles in all eukaryotic organisms?
It is the Promoting Factors enzyme that does this
What are the two disjunctionsthat can occur?
Mitotic or meiotic, depending on whether ordinary cell division or gamete production is involved.
What are two types of eukaryotic cell division?
Meiotic and Mitotic [ Meiosis and Mitosis ] are the two Types.
What is the primary functional differences between mitotic anaphase and meiotic anaphase II?
functionally they are pretty much the same. overall the number of chromosomes is different.
How does the arrangement in chromosomes at meta phase differ in mitotic division and the first division?
in meiotic cell division the chromosomes are not aligned in the middle like meta phase.
Is Down syndrome more severe in mitotic nondisjunction or meiotic nondisjunction?

What do you get from meiosis that you don't get from mitosis?
Mitotic cell division produces two genetically identical daughter cells that are genetically identical to their parent cell. The daughter cells that result from mitotic cell division are 2n, having two sets of chromosomes. Meiotic cell division produces four genetically non-identical cells that are 1n, having only one set of chromosomes. The parent cell for meiotic cell division is 2n.
