What else can I help you with?
Would two brothers have the simIlar dna?
It is very unlikely that two brothers would have babies with the same DNA. That could only happen if identical twin brothers married identical twin sisters, and even then the mixing of DNA during reproduction makes this an extremely unlikely outcome.
Do brothers and sisters have similar finger prints?
No, siblings do not have identical fingerprints. Each person's fingerprints are unique and are formed by random variations in the womb. While there may be similarities between siblings' fingerprints due to genetics, they will not be identical.
Can brothers and sisters share the same DNA?
No, unless they are Identical Twins. Normal siblings will on average share 50 percent of their genetic material, since they get half of their chromosomes from their mother and half from their father.
Do studies of identical twins show that there is a relationship between genetics and sexuality?
Yes. Absolutely. In the Kallman study in 1952, Kallman found that of the 37 identical twins classified they all not only had the same sexuality but were similar in their sex practices. The next large study of note (and the most recent) was performed in 1991 by Bailey and Pillard. They decided to look for homosexuals to apply to a study and asked them if they had an identical twin, fraternal twin, or an adoptive brother. Then they asked for the sexuality of the brothers of the homosexual men. The scientists believe that if genetics is a factor, we should see a much higher amount of homosexual behavior in identical twins than in fraternal twins who only share as many genes as normal siblings. Also, if genetics play a part in sexuality, then there should still be a higher concurrence in fraternal twins than in adoptive brothers who share no genes. 52% (more than half) of the identical twins of a homosexuals were also homosexual. As the average amount of people that are homosexual is around 10%, this indicates that genetics play a very large role in sexuality. 22% of the fraternal twins of homosexuals were also homosexual. Again, this is in comparison to the 10% of the population that is normally homosexual, so even with brothers that are not identical genetics make it twice as likely that a person will be homosexual if they have a homosexual sibling. Finally, with adoptive brothers that shared the same home, only 11% were homosexual. When no genetics are involved, the rate of homosexuality dropped down to where it would be expected to be - the national average of 10%.
Are identical twins the same in their genes?
Nope. Research has shown that DNA in twins is different, especially in copy number varitations, which refers to when a gene exists in multiple copies, or a set of letters in the DNA is actually missing. These variations are suspected to lead to increased defense against some infections, or vulnerability to others. http://www.nytimes.com/2008/03/11/health/11real.htmlTheir genes are very similar.Because the two embryos are the result of a single egg/sperm combination, they have the same genetic origins. They have the same DNA. however, they don't have the same finger printsAlmost! While the sequence begins identical, epigenetics (environmental type factors) appear to cause them to change over time.
Why don't brothers and sisters look identical to each other?
Brothers and sisters are not identical because they have different combinations of alleles.
Are Johnathan and Drew on the Property Brothers Identical twins?
Yes, Jonathan and Drew Scott are identical twins. They are known for their roles on the HGTV show "Property Brothers."
If identical brothers impregnated identical sisters would the babies be identical cousins?
No, because not all genes are selected from the parents. Identical brothers/sisters have exactly the same genes...the egg split just after genes were selected. They will sure look similar, though.
Bill and Brian are identical twin brothers?

What are three identical brothers called?
Triplets are three identical brothers born at the same time.
