A) Male offspring will be normal; female offspring will have the disorder B) Both male and female offspring will be normal C) Male offspring will have the disorder; female offspring will be normal D) Both male and female offspring will have the disorder

The provided question is incomplete as the essential information and pedigree is missing, however the complete question is attached as the image.

The correct answer would be - option b. both male and female offspring offspring will be normal.

Explanation:

Extranuclear inheritance is the transfer of the genes that are present outside of the nucleus. This type of transfer of gene is termed as cytoplasmic inheritance as it is transfer from the cytoplasm of the gametes that is something that comes from the maternal side.

As it mentioned above it is something that is transfer from the mother side as it is related to the cytoplasm of the gametes. In the given pedigree male is infected and female is normal so there are no chances to transfer genes that are presented in cytoplasmic as female is normal.

Thus, the correct answer is - option B.
