Solution

It is the female reproductive cell, which usually carries more cytoplasm and cytoplasmic organelles than the male cell and hence, naturally would be expected to influence Non-Mendelian traits. Since in the present case, the male parent (not female) had mutation in mitochondria, there are negligible chances of the mutation being inherited.
