Zygotic meiosisis the one occurs in
the haplontic life cycle.
Gametes from haploid individuals
unite forming diploid zygote. The
zygote meiosis and
generates four cells that by
mitosis into adult individuals.
Therefore the zygoticmeiosis the cell
undergoes meiosisis the zygote
the gametes are formed mitosis.
Gametic meiosis is in which meiosis
produces , i.e., haploid cells
that of which can unite
another gamete forming the . It
occurs in the haplobiontic life
cycle (e.g., humans) in which the
is diploid and meiosis
gametes.

Sporic meiosis happens metagenesis
(alternation of generations,
diplobiontic life cycle). In life cycle
cells from diploid individual (called
sporophyte) meiosis producing
haploid spores donot unite with
others instead develop by mitosis
haploid individuals (called
gametophytes). this life cycle the
are made by mitosis cells
of the gametophyte.
