Question

according to biological science, no two humans can be identical coz of the 1000000's of ways in which homologous chromosomes combine, then y do we still have people who r identical on planet earth.. pls sb answer

Answer 2

Similarity between 2individuals is due to the genetic sequence they share.( individuals with in races(Mongloid/European/Negriod) share some genetic sequence which make them externally similar to some extent (identical))
The more similarity in gene sequence the more identical will be 2 individuals, as we see in the case of IDENTICAL TWINS(they develop from a single zygote).
Clarifying- Cloned animals are exact copies of the parent from which the nucleus is taken.
Other similarities which happen are just by chance........

Answer 3

actually in what i have read that there is extreme rare cases that 2 in a 8 billion people may share most of the genetic material but it is still not 100% but they are almost the same.

Answer 4

no two persons are "identical" on planet earth except identical twins. People often look similar but that doesnt make them identical. If you dont have an identical twin, there is no chance that a person identical to you will exist.

Answer 5

It is imposible for people to be identical weather cloning or twins it dosnt matter. Twins have different fingerprints and with cloning it all depends on the enviroment. so althogh verry close simalarities may occur no two people are identical.

Answer 6

Prasadwaghmare, there r some twins that do not specifically meet up the level of being identical. they r twins of the same egg, but why the difference.....now please i would like for you to explain the difference between identical and similar..because identical also means similar acccording to dictionary.com...there r 100's of millions of individuals on this planet, some defy the biological science not only in the sense of similarity but in other aspects of life..

Answer 7

No two persons can be exact xerox copies of each other. I used identical in the sense of their genetic make up and phenotype. Now if the twins have developed from a single egg, their genetic make up will be 100% similar, and so will be their phenotype. There are exceptions to this rule however, but how does that happen is not clearly known. Even those twins with identical genes, dont necessarily become identical human beings, because the persona, lifestyle choices and many other things.

Answer 8

well explained Prasadwaghmare, i give u kudos for it..you have a point there.
