More info
- Reason why it can only be inherited by the mother is when the egg cell is being fertilized the mother and fathers genetic code mix together but the father mtDNA stays behind leaving the egg with only the mothers mtDNA.

Importance
Mitochondrial DNA
-- A tool that provides evolutionary changes over time in organisms alike
--Helps scientist better understand our genes and mutations so the can come up with better ways of preventing the disease
--Help to conserve endangered species
Gene Comparisons
Works Cited
- Everyone has Mitochondrial DNA and it was passed down by this one woman.
- mtDNA is only passed on by the mother
- Mitochondrial DNA are tiny structures that can help the cell produce energy and many other things

- When comparing human genes to other organisms it gives scientists a better understanding of human structure and function
- Allows scientist to fight off human disease and evolutionary change
- By having comparative genes it will allow scientist to improve human health and prevent disease
- DNA sequence is made up of four building blocks adenine A, thymine T, cyosine C guanine G

Homeotic Genes
- DNA sequences that influence an organism's development
- Called homeoboxes
- Hox genes are grouped one after another

Genetic mutations can occur in homeotic genes causing entire body parts to form at the wrong location. Flies can develop legs in the place of their antennas. A human mutation of homeotic genes is autism.
