Whereas nuclear DNA (the famous double helix, which encodes most of the genome) is inherited from both parents, mtDNA is inherited solely from the mother. At birth, a female infant’s ovaries already contain all the eggs she will ever have. During the reproductive cycles that begin at pubert...
What is the difference between autosomal and mtDNA tests? Does X-DNA affect autosomal inheritance? Why is autosomal DNA different for siblings? How can scientists distinguish between autosomal and sex chromosomes via banding? How can genetic disorders be autosomal dominant and autosomal recessive?
How is autosomal DNA passed down? What is the difference between autosomal and mtDNA tests? Why do populations have variation in certain traits? How is our autosomal DNA expressed? Why can't genes change later in life? Describe heredity ...
Clearly he just inherited more of the same DNA as John’s mother from their common grandparents. Conversely, he inherited less DNA shared with Dick’s mother from his other grandparents. On the left is a comparison of my first cousin Henry with both Dick and John. The amount he shares ...
Most DNA is contained in the cell nucleus (nuclear DNA), but it can also find a minor quantity in the mitochondria (also known as mitochondrial DNA or mtDNA). Mitochondria are cell structures that transform energy from meals into a form cell can utilize. What are the building blocks of ...

(1) discovered, through careful genetic analysis of patient family trees and Sanger sequencing of patient mito-chondrial DNA (mtDNA), that a specific mtDNA mutation is the cause of LHON, hence founding the now burgeoning field of mitochondrial medicine (2). Since then, researchers have ...
What is the difference between autosomal DNA and mtDNA? How is germline gene editing different from somatic cell editing? How would you know if two chromosomes were homologous? How are spontaneous mutations and genetic engineering similar and different? How do somatic versus germline gamete mutations...
What is the difference between autosomal and mtDNA tests? How are dominant genes indicated? Why are genetic mutations important to genetic variation? How do you find the frequency of a recessive allele? Are autosomal recessive traits x-linked? How are alleles and traits related? Why is the homo...
