Science down the birth of twins?
Answers:
The development of twins.
A single ovum is released from the ovary.
The ovum is fertilised by one sperm.
The zygote divides to form an embryo.
The embryo splits into two the same embryos.
Each embryo completes its development.
So, twins are exact because they each contain copies of like peas in a pod set of genes.
i'm a twin and have no clue
if the egg spits contained by half u seize twins
Two eggs can be fertilized or one egg splits in partially.
Identical twins are one original egg and sperm that divided for some apology (unknown) to carry on nouns as two seperate entities. They are always indistinguishable sex.
Fraternal (non-identical) twins come from mothers who release two eggs monthly rather than one. Both eggs receive fertilised and develop as two seperate entities. They can be the same or different sexes.
it is when two sperm enter the egg at exactly indistinguishable time of conception
the answer above mine is correct..but that is not the one and only possible cause..
it may come to pass that two eggs are fertilised by two separate sperm cells..within tht case the twins wud be call fraternal twins.n may of different sex even.let alone the looks.
within the answer above.u will get what are call identical twins.like sex..n to a large extent.similar looks.
demeanour however maybe on the two poles of our planet..
hope tht answers ur put somebody through the mill.ciao!
There are 2 types of twins identical and fraternal.
Fraternal twins are when you enjoy 2 diffrent eggs that are fertilized by differnt sperm at the same time. When one twin is mannish and the other is female this is what have happened.
Identical twins is when one egg is fertilized by one sperm and during the developmental process of the zygote it splits within to 2 to become to separate embryos, but with similar DNA.
Conjoined twins (Siamese twins is no longer used as a term to describe this) arise from the egg-splits-in-two scenario, not from the two- separate-eggs scenario. i.e. they are other identical.
Have a look at :
http://www.babyworld.co.uk/information/p.
In females..respectively ovary usually produces ovum alternately.but in completely rare cases, both the ovaries produces ovum at matching time..thus both can gett fertilise.and twins can come ..this may be the reason.
one comes out consequently the other.
twins simply develop when a fertilised egg splits into two and both parts grow separately
2 egges fertalized at the same time or one egg splits into two
the result two babys ie twins
