11 sperms and 21 eggs
Identical and fraternal twins typically share many similar characteristics
doubtful Yes, only fraternal twinning (caused by releasing more than one egg) has a genetic connection, and that connection only holds on the mother's side. So, many twins are born with no family history of twins at all.
12 eggs= a dozen
I know of two pairs of twins in the bible Jacob and Esau, and Thomas and his twin.
1-4 eggs
there are two types of twins-- fraternal and identical. Fraternal twins are genetically unique, and they usually have physical differences. Identical twins are identically identical, such as a clone, and have exact physcial characteristics, excluding weight and scars etc.
To have twins, it's just two. whether they're identical or not depends on if they're two girls, two boys, or one boy and one girl. To have twins, it's just two. whether they're identical or not depends on if they're two girls, two boys, or one boy and one girl.
fraternal and identical
No, the likelihood of having twins is determined by the release of two eggs by the woman's ovaries during ovulation, which can result in fertilization by two different sperm. It is not related to the number of times a man ejaculates during intercourse.

He has fraternal twins. Boy and girl. :)
There are many twins that don't look alike. They are called fraternal twins.
In the case of fraternal twins, two separate egg cells are fertilized by two different sperm cells. For identical twins, a single egg cell is fertilized by a single sperm cell, but it splits into two embryos during early development.
Twins can look alike due to sharing the same genetic material and inheriting similar physical traits from their parents. Identical twins result from a single fertilized egg splitting into two embryos, leading to nearly identical DNA. Fraternal twins, on the other hand, are the result of two separate eggs being fertilized by two different sperm cells, which can result in less resemblance between siblings.
Normally, a woman normally releases ONE egg per menstrual cycle. On occasion, a woman will release two, which would result in fraternal twins if both eggs are fertilized.
For humans, in most cases, one is released every cycle. If more than one is released and fertilized, the resulting newborns will be fraternal twins, triplets, etc.
Only one sperm cell can fertilise each ovum. After that no more can get in.
