Two individuals that develop from the same zygote are called identical twins. If they develop from two separate zygotes, they are fraternal.
Identical (monozygotic) twins develop from one zygote (fertilized egg) that splits into two embryos.
Population
Yes they are
A zygote is the combination of the half DNA data from both "parents" and if each have a total of 10 then the Zygote receives 5 from each parent and ends up with the same as its parents' number of chromosomes.

Identical twins form from the same fertilized egg (zygote). When the zygote has divided a few times and formed a ball of cells, something causes this embryo to split in two. Each half then goes on to develop into a person. So the twins have identical genes. A technical name for such individuals is monozygotictwins.Fraternal (or dizygotic) twins develop from two zygotes, formed from two different eggs (ova) fertilized by two different male gametes (sperms). So they are not necessarily any more alike than any other siblings.
No two individuals have the same genetic content, with identical twins being the only exception. Even, they if brought up in different envoironment can develop changes, brought baout by environment. Such differences among individals at the genetic level is known as " variations".

I searched this in google:A twin is one of two offspring produced in the same pregnancy. Twins can either be monozygotic, meaning that they develop from one zygote that splits and forms two embryos, or dizygotic, meaning that they develop from two eggs, each fertilized by separate sperm cells.That is gemellology.
A group of individuals of the same species living in a particular place is called a population.

The group of individuals used to represent a population is called the sample. It should have the same statistics as the population, though be of a smaller size.

Dolphins are mammals; their reproductive process is essentially the same as that of human beings, even if they happen to be in the water at the time. The zygote of a dolphin develops in the uterus of the mother dolphin.
