A) Autosomal
B) Cytoplasmic
C) Y-linked
D) X-linked
Correct Answer: B
Solution :
The more maternal influence can be expected in the cytoplasmic inheritance (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 a large amount of cytoplasm containing many such 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 cells (sperm or pollen) consist 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. Genes located on Y-chromosome are called Y-genes and their inheritance is called Y-linked inheritance. This carries the paternal influences. A gene located in the X-chromosome is said to be X-linked and its inheritance is called, X-tinked inheritance. In this, a male transmits his X-chromosome only to his daughters, while a female transmits one of her X-chromosomes to the offspring of both sexes.
