Syncytium Chorialis

Chorionic syncytium - (nrk.) is the area of ​​fertilization of one female organism by the maternal organism of another female organism with the help of two gametes fused into a single whole. This form of fertilization was first described by Conrad Morgan in a study of twins who ovulated simultaneously on both sides, so they had two fertilized eggs.

From previous studies it is known that due to enzymatic breakdown of the egg membrane, these eggs unite and begin to divide at the zygote stage. The second sex cell also penetrates into the new zygote, and since the chromosomes from the two gametes are carried along with the fluid, this forms diploid cell tissues, which from that time on always divide into twice the number of genetic sets. Since each cell has its own genetic set (23 pairs of chromosomes), this number of cells are truly identical.

Thanks to this union of two fertilized gametes, male and female chromosomes are found in the same cell. Thus, organisms that are fertilized thanks to the chorionic syncytium are called homozygous, because both fertilized cells bear the genetic characteristics of only one organism.

Syncytium Chorial is a normal phenomenon for fertilization of monozygotes
