A) plastids and inherited
B) plasmid and not inherited
C) mitochondria and inherited by male
D) mitochondria and inherited by female
Correct Answer: D
Solution :
Extra nuclear genes present in mitochondria, plastids. Kappa particles etc. the extra nuclear genes or cytoplasmic inheritance is different from normal nuclear inheritance. The very basis of this difference is the unequal contribution made by father and mother as zygote receives most of its cytoplasm from the egg and very tittle on no cytoplasm from the sperm. Thus, it has two distinct features (i) It is more or less material inheritance, ie, here only the female parent contribution towards inheritance. (ii) Due to the participation of female, only the result of reciprocal crosses is not the same.
