Does twins start there period at the same time?
Genetics aren't the only thing to influence when girls start their period. It's entirely possible that one twin starts her period before the other (even if they are identical).
Why does identical twins not have the same weight and Skin colour?
Eye colour is caused by genetics whereas the weight of a person depends on how they life their life (how healthily they eat or how much exercise they do) so it is an environmental variation. Identical twins have the same genes so have the same eye colour.
What does fraternal twins and identical twins have in common?
Identical twins are twins that develop from same egg. These twins have same genome, also they have same physical appearance with minimal differences.
Similar twins are true twins or not?
i would have to say no because i am an identical twin and when you hear twin you think of identical ones. also fraternal twins aren't really twins because they are 2 separate babies that just happened to be fertilized at the same time.
Are fraternal twins technically clones?
No. Not even close. Fraternal twins result from two eggs fertilized by two sperm at about the same time and being implanted in the uterus together. They are siblings.Not even identical twins, by the way, can be considered as clones, because cloning involves the removal of genetic information from one cell with its transfer to another cell. Identical twins involve splitting, not cloning.
What is the differences between identical twins and fraternal twins?
Identical twins arise from a single fertilized egg that for some reason split itself in two. Identical twins have exactly the same genetic make-up.Fraternal twins arise from two separate eggs. Sometimes both of a woman's ovaries will produce an egg cell at the same time. Each of these is fertilized by a separate sperm cell (of which there are always plenty) so they have different genetic make-up. They may share the same womb and be born at the same time but are no more closely related than true brothers.
Do you get your period on the same year on the same day as your mom?
No, you do not get your first period at the same age that your mother got her first period. Everyone develops differently and at different rates, even if you took identical twins they wouldn't reach menarche at the same time.
Can genes of two persons be identical?
The genes of identical twins are identical because the twins come from one egg that has split after fertilization. Fraternal twins are not identical since they come from two eggs but have occupied the mother's womb at the same time.
What is the difference between idetical and non idetical twins in the way they are found?
The difference between Identical and Non-Identical twins is that Identical twins share the same placenta and are basically identical to one another. Non-Identical twins do not share the same placenta in the womb and two eggs fertilized at time of conception as opposed to one egg splitting in the case of Identical twins. I think that covers the basics. Hope this has clarified things for you.
Are non-identical twins occur when egg cells turns into embryos on their own?
No, non-identical twins are fraternal twins. They are created when two eggs are fertilized at the same time and become embryos. Identical twins are when a fertilized egg splits into two on its own.
Does twins start there period at the same time?
Genetics aren't the only thing to influence when girls start their period. It's entirely possible that one twin starts her period before the other (even if they are identical).
What kinds of twins are there?
Identical and Fraternal There are identical and fraternal. Fraternal twins happen when 2 different embryos start growing at the same time, so you get a brother and a sister or 2 sisters or 2 brothers that are the same age. Identical twins happen when 1 embryo splits into 2 embryos when it is only a few cells big, so both babies have the same genes.
Why does identical twins not have the same weight and Skin colour?
Eye colour is caused by genetics whereas the weight of a person depends on how they life their life (how healthily they eat or how much exercise they do) so it is an environmental variation. Identical twins have the same genes so have the same eye colour.
What is the genetic difference between identical and non identical twins?
Identical twins are formed by the separation of the same embryo containing same genetic coding. thus the the twins are identical as formed from the same embryo. But this is not the case in the non-identical twins as they are formed from the individual embro each having different genetic coding.
What are seven babies born at the same time with the same mother called?
Twins Also, they are called identical twins if they come from the same egg
Do twins have to be born on the same day?
twins just have to develop in the same womb at the same period of time. When they are born has nothing to do with it.
Can identical twins be of different sexes?
They can be. While identical twins always have to be the same gender, fraternal twins usually are not. However this is not always the case. Identical twins occur because they inhabit the same egg. Fraternal twins because two eggs were fertilized at the same time. So fraternal twins could be the same gender, but usually they are of the opposite gender.
