copying process that does not interfere
with cell ploidy.
- Concerning their final
products (daughter cells and
their ploidies) what are the
differences between mitosis
and meiosis?
In mitosischromosomes, d one cell, for exampluplicates its e, with 2n
chromosomal set antwo other cells, each with d divides g2n enerating
chromosomes too. In meiosis, one
diploid cell (2n) duplicateschromosomes too, but four cells with n its (^)
chromosomes are generated.
- Concerning their biological
function what is the difference
between mitosis and meiosis?
The main biological function of mitosis is

There is a shappens in zygotes opecial type of meiosis thatf some algae,
protozoacalled zygotic meiosis, has the functionns and fungi. This meiosis, (^)
of reducing to a half the number of
chromosomes of adult individuals that
will be formed from the zygote. In
species with zyindividuals are haploid and they formgotic meiosis the adult
gametes by mitosis. These gametes
fuse in pairs with diploid zygote that, thothers and generate aen, undergoes
meiosis to restitute the normal ploidy of
adult individuals.
- For the biological diversity
is mitosis or meiosis the more
important process?
Meiosis is the cell division pallows the formation of gametes torocess that
sexual reproduction, with aleatory
separation oindividual homologous pairs. Tf each chromosome ohesef the
gametes can fecundate gametes from
