they are alike by leukemia involving the bone marrow but different by not having the same problems.
Generally, each person has his or her own genetic makeup. Identical twins can have a very similar DNA>
Non-identical twins are more like normal siblings. Identical twins have the exact same DNA, so will be very similar in appearance. Their environment will cause them to have very slight differences, such as different fingerprints and freckles.
identical twins raised in different cultures, haploid plants made diploid by colchicine also share similar genetic heredity.
Identical twins are a useful tool in study of effet of genes and environment on genetic traits including human behaviors.This study is done by keeping identical twins in same environment and in different environments. Experiment performed by this technique indicate that genes have 66% effect on behaviors etc. while environment have 33% effect.This is called concordance.Identical twins show similar behavior (66%) even if reared apart in different environments which is due to same genes.
they are not same but similar as they bear alleles of same gene.
no. every human has different fingerprints, twins or not
No. Similar but proveably different in laboratory analysis.
They are twins!
Identical twins are formed when an egg fertilised by a sperm splits in half to form two different embryos.
if they share 1 heart then yes they do. but if they have different hearts then they do not
If they were not then they would not be called identical twins!
Appearance and basic behavior
Generally, each person has his or her own genetic makeup. Identical twins can have a very similar DNA>
No they do not. Identical twins have identical DNA structure, and therefore they have very similar cell structure, leading them to have vastly similar organs (same size, health issues, etc.). However, everyone, even identical twins, do not share the exact same organs. Some identical twins get migraines, while the other doesn't. In some cases, one twin will be homosexual and the other heterosexual. In any case, by nature, identical twins do not have identical brains, and by nurture they experience different things, learn different things, and process information in different ways, resulting in the twins having differing opinions, etc. No two brains are exactly alike.

They are similar in size.
They have the same DNA.
