Question

If you have siblings (brothers and/or sisters), all of you have the same mitochondrial DNA.

Answer 1

hmm,well it is not true actually.All your brothers and sisters will have a different DNA from each other and tts why there is no one person who is exactly the same.

Well i tink u're still blur abt my ans so i'm gonna elaborate..

well all of our cells multiply and when the egg and sperm meets we all start to grow and that's when our DNA is produced.There is no one person with the same DNA because of the genetic varibility in fertilization.Since there is this genetic varibility brothers and sister will have about the same DNA but not totally the same.This then links to the mitocondrial DNA.Our DNA is the same for all of our cells and our DNA IS ONLY FOUND IN THE NUCLEUS not in the mitochondrial.

mitochondrial DNA is ancient bacteria but now in our body there is no longer anymore DNA in the mitochondrial.

Answer 2

yep it is passed on matternally,..

but if you have a brother or sister in law they will have a diff mtDNA

Answer 3

It passes only from the female except in exceptionally rare cases.

Answer 4

umm chosten..you need to catch up in the world of genetics.. Mitochondrial DNA exists in humans..and is passed maternally because sperm are not large enough to accomodate mitochondria in then head region where capacitation occurs. Several strange diseases are due to defective DNA in mitochondria and of course all children of that mother will inherit that  defect..   You need to read about mitochondrial Eve..and how we can trace back the human lineage .based on the passage of mitochondrial DNA by the female side  

Answer 5

all of your mothers kids will
