Respuesta :
During meiosis I, in maternal and paternal systems, chromosomes fuse together during the process called synapsis to form a tetrad.
In sexually reproducing organisms, meiosis includes a sort of cell splitting of germ cells that results in gametes like sperm or egg cells. Four cells with just one duplicate of each chromosome are produced after two cycles of division.
Genetic material from each chromosome's maternal as well as paternal copies crosses over before division, creating new code combinations for each chromosome.
A zygote, a cell having two duplicates of each chromosome, was created when the haploid cells generated through meiosis between a male and female combine during fertilization. Meiosis produces four daughter cells, each of which has half as many chromosomes as the initial parent cell, after two rounds of cellular division that follow DNA replication. The two meiotic processes were meiosis I and meiosis II.
