Aman has a mutation in a mitochondrial gene encoding a subunit of the atp synthase complex. the mutation leads to a defective atp synthase that is not able to synthesize atp effectively, and this in turn leads to extreme muscle weakness in the affected individual. the man's wife is phenotypically normal. they have two boys and two girls. what proportion of their children is expected to have the disease?

Refer to the family pedigree shown here. in generation i, one parent is affected by the gene mutation and one parent isn't. in generation ii, all three children are affected by the gene mutation. what can you conclude about this gene mutation? a. all children born in future generations will be affected by this disorder. b. this gene mutation is a dominant disorder. c. this gene mutation is a recessive disorder. d. the generation i mother is a carrier of this gene mutation.
