    In which mode of inheritance, do you expect more maternal influence among the off springs?

    A)  Autosomal

    B)  Cytoplasmic

    C)  Y-linked

    D)  X-linked

    Correct Answer: B

    Solution :

     The more maternal influence can be expected in the cytoplasmic inheritances (i.e., the inheritance of genes contained in the cytoplasm of a cell, rather than the nucleus). The reason is that the female reproductive cell or the egg has large amount of cytoplasm containg many organelles, which contain their own genes and can reproduce        independently (e.g., mitochondria and chloroplast) and, which are consequently incorporated into the cytoplasm of all the cells of the embryo. The male reproductive cell (sperm or pollen) consists almost solely of a nucleus. Cytoplasmic organelles are thus, not inherited from the male parent. This is why, the cytoplasmic inheritance is also called maternal inheritance.
