Interesting facts about non-egg twins
Factors that increase the likelihood of other twins eggs
Unlike what people often think of being twins, they will have to be identical in appearance and part of each other's personalities. But actually this only happens to twins of the same egg, while the twins other than the egg will have quite characteristic differences.
Non-identical twins are often not the same in appearance, personality, and interests
Non-identical twins have the same genetic makeup as that of other siblings in the family. Therefore, with only 50% identical DNA structure, each person receives half of the DNA from the mother's egg and half from the father's sperm.
The different twin fetus develops in an independent direction, so each baby will have its own placenta to provide nutrients. At the same time, located in two different amniotic membranes in the womb of the mother.
The gestation period of a normal pregnancy lasts about 40 weeks of gestation, but with other twins eggs will be 37-38 weeks shorter so the average weight of twins is 1.9kg.
Just like any sibling, different egg twins can look very different. From facial features, physique to personality or hobby. Therefore, you should not be surprised to see two twins but completely different.

As adults, each with different twins eggs will have different developmental tendencies.
An egg-different twin is when a mother's body has 2 eggs that release at the same time during a menstrual cycle and are conceived with 2 separate sperm cells. Two babies will develop together in the mother's womb, but each baby will develop in its own independent directions
The sex ratio of non-identical twins is 50:50, meaning that half of non-identical twins is 1 boy 1 girl and the other half is 2 boys or 2 girls. Sex is formed based on the father's chromosomes: XX is female, XY is male.
This is the most common case when there are twins with different characteristics, in addition there are a number of twins with a relatively low rate of different eggs.
Different period fertilization
It is also having twins, but the difference here is that the two eggs will meet two sperm at different times. This means that an egg meets a sperm that forms the first zygote, and when the zygote develops for a few weeks, the second zygote is formed. So, after giving birth, one baby will be sturdy and bigger than the other.
Twins are different from eggs - different from father
A mother can have a different twin of a twin from two different men, and a different case of multiple fertilization explains this problem. Accordingly, when a woman becomes pregnant and ovulates again, this egg fertilizes the sperm of another person and develops in parallel with the previously formed fetus.
