  1. Correct Answer – B
    In the present case the male parent (not female) had mutation in mitochondria, there are negligible chances of the mutation being inherited. 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.
