What else can I help you with?
What will happen if cell do not undergo meiosis in sexually reproducing organisms?
There will be no reproduction
What happen during meiosis?
the process of cell division in sexually reproducing organisms that reduces the # of chromosomes in reproductive cells
When and in what cells does meosis happen?
Meiosis occurs when diploid cells produce haploid daughter cells and takes place in sexually reproducing organs.
What would happen if organisms stopped reproducing?
it becomes extinct
What would happen if meiosis did not produce sex cell?
The individual would not be able to reproduce sexually.
Is natural variation only in wilod organisms in nature?
No, humans are born naturally variant. Through independent orientation of chromosomes and crossing over in meiosis through random fertilization matching gametes, both male and female, to random mutation all sexually reproducing species are variations. Asexual species also mange to vary through mutational events that happen often enough for variation to be assured.
How can micro evolution happen?
By simple genetic recombination for one. microevolution is just evolution and evolution is the change in allele frequency over time in a population of organisms. Just change over time short of speciation and especially valid for sexually reproducing organisms who always change allele frequencies through coitus and reproduction.
What happens in meiosis that does not happen in meiosis 2?
DNA is copied in meiosis 1.
Where within the testes does meiosis take place?
meiosis occurs in organisms so that they can reproduce sexually, its a process of cell division during which the nucleus divides into four nuclei, each of which contains half the usual number of chromosomes. and it occurs in both males and females
What happens in meiosis 1 that does not happen in meiosis 2?
DNA is copied in meiosis 1.
What happens in meiosis 1 that doesn't happen in meiosis 2?
DNA is copied
Does meiosis happen in all animals?
no
