how are triplets and quadrulets etc made?

Question

we all know how twins are born but is the "process" the same as it??

Answer 1

Identical: Identical triplets occur in almost the same way as identical twins, but instead of the egg dividing once, one of those halves divides again to create three genetically identical babies. In the rare cases of identical quads, both halves would divide to form 4 identical babies. The Dionne quints of Canada were identical quintuplets, the only set in the world.

Fraternal: Fraternal triplets would occur if three eggs were released by the mother and each fertilized by a different sperm. The same would occur for fraternal quads if 4 eggs were released and fertilized, as well as 5 being released for quints. The chances of having spontaneous (not from IVF or fertility drugs) quads and quints isn't as common, spontaneous quints are quite rare, fraternal or otherwise.

Mixed: Higher multiples can often be a combination of identical and fraternal. The most common type of spontaneously conceived triplets are "a pair and a spare", two identical and one fraternal. Two eggs would be released by the mother and fertilized, and only one would split to form identical twins. This can occur with quadruplets, you could have 2 identical and 2 fraternal (three eggs released, one splits, this seems to be the most common of all fraternal), 2 sets of identical twins (2 eggs released, both split), or 3 identical and 1 fraternal (2 eggs released, one splits once, and then again). The same can happen with quintuplets, you could have 2 identical, 3 fraternal (which seems to be the most common of all fraternal), or any combination of identical and fraternal, although it is very rare to see more than 2 identical in a set of quints. Combinations for sextuplets and higher would be similar, although it is highly unlikely to see identicals in sextuplets and higher since almost all of them come from fertility drugs. (Although there was one case where the sextuplets were 3 identical and 3 fraternal).
hope this helps

Answer 2

Some are natural, while others are from insemination. The insemination is the most common cause of multiple births these days. They fertilize about a half dozen eggs at a time, and implant them in the woman. Which most dont take & she loses. But then there are the times when they all stick & hence the multiple babies. Or the egg splits making that one specific egg identical twins.
Hope this helps answer your question.

Answer 3

Well I would say that identical triplets and quadrulets is the same process but instead of the fertalised egg splitting once, it does so several times. Unidentical triplets and quadrulets again I would say is the same process as unidentical twins, more than one egg is relased from the ovaries and therfore fertalised to make twins, triplets e.t.c.

Answer 4

quadtrults are made when 2 eggs come from each ovary and split in half

Answer 5

eggs split or many eggs, many sperm making their way and being successful at it ... all at the same time.

split eggs are identical
more than one egg is fraternal

Answer 6

Same way

Answer 7

Same way as singlets!
