Subsequent generations show greater improvement in genetic characters.

1.	Subsequent generations show greater improvement in genetic characters. It is seen in higher animals particularly. This is due to: (A) Crossing over process of sexual reproduction. (B) Living in an area for many generations. (C) Due to pressure for improvement of characters from peers. (D) Asexual reproduction brings improvement.
Answer» (A) Crossing over process of sexual reproduction. Subsequent generations show greater improvement in genetic characters. It is seen inhigher animals particularty because, in sexual reproduction of higher animals gametes are formed by meiosis cell division. This meiosis shows crossing over at one particular stage [Meiosis I → Prophase I → pachytene] where new and better traits are expressed
