Question

base your answers to questions 11 and 12 on the information below and on your knowledge of biology. mitochondria are organelles present in most complex cells. the diagram below illustrates a typical mitochondrion in cells. 11. unlike most other organelles, mitochondria contain their own dna. this dna is in the form of a double - stranded, ring - shaped molecule that can replicate. the number of mitochondria in a cell can increase when mitochondria reproduce. mitochondrial dna mutates. some of these mutations have been linked to certain diseases in humans. mitochondrial dna is passed on to children through their mothers. the chart to the left illustrates this process. mitochondrial inheritance father with disease mother with disease (all mitochondria mutant) children do not have the disease children have the disease provide evidence from the mitochondrial inheritance chart that supports the claim that mitochondria are usually inherited from the mother.

Explanation:

When the father has the disease (due to mitochondrial - related issue), children do not have the disease. But when the mother has the disease (all mitochondria mutant), children have the disease. This shows that the mitochondria - related trait is passed from the mother to the children.

Answer:

When the father has a mitochondrial - related disease, children do not have it, while when the mother has a mitochondrial - related disease (all mitochondria mutant), children have the disease.
