Is there any reason for the variation in mitochondrial DNA size?

Question

As my textbook *An Introduction to Genetic Analysis* points out, yeast mitochondrial DNA has approximately 78 kb of genetic data, while the human mitochondrial DNA contains 17 kb. Is there any evolution reason for this drastic change in size? Also, are there any particularities about mitochondrial function that have been compromised with this reduction in size?

Answer 1

Endosymbiotic transfer is the current theory. So I’m more complex organisms such as humans more of the DNA Which was Coded in the mitochondria have been transferred to the main genome.

also I don’t believe there’s really a correlation between the size of the mitochondrial DNA, and the number Of jeans, surprisingly.
