Answer:
His sisters son
Explanation:
Mitochondrial DNA are small circular chromosomes found inside the mitochondria. They are passed exclusively from the mother to children through the egg cell therefore it is maternally inherited.
In the given question. Mitochondrial DNA of an extended family was sequenced and compared to a single male.
His sisters son will match because the person and the sister will have similar mitochondria since they have the same mother. The sister will pass it down to her son.
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).
Answer:
Epigenetic effects can be caused by DNA heterochromatin and/or histone silence or activate.
As such, they can different chromosomes or certain chromosomal regions and be responsible for parental imprinting or influencing gene activity in oxidation and reduction.
Patterns of nucleotide demethylation and hypermethylation are often activate when cancer cells are compared to normal cells.
Explanation:
Cells acquire various patterns of gene expression during differentiation to adapt to a changing environment. Epigenetic and genetic alterations are considered as two independent mechanisms that participate in the onset and progression of cancer. Epigenetic mechanisms can be as important for biological events as genetic mechanisms, which do not imply a change in the DNA sequence, but do have an important role in the modification of gene expression.
