Do explain me gametic meiosisand zygotic meiosis also tell which phylum animals show this with proper examples...

The meiosis is of three types, depending on the stage where it occurs. The main difference between these three types of meiosis is:
In gametic meiosis the process of meiosis occurs during the formation of gametes and results in haploid gametes formation. Eg in sexually reproducing organisms
In zygotic meiosis the process of meiosis occurs in a zygote and again results in haploid individuals. Eg in Algae
In sporic meiosis, the division occurs during sporogenesis and results in the formation of haploid number of spores. Eg in ferns and mosses
