Solution

1: Ovipary refers to laying eggs that bear the young ones. Birds are the oviparous organisms.
2: Ovoviviparity refers to the developmental process wherein the eggs are hatched to give release the young ones which are then carried inside the mother\'s body. Ex: Snakes
3: Ovoviviparous refers to the group of organisms that exhibit ovoviviparity.Ex: snakes
4: Viviparous refers to group of organisms that bear the young ones in mother\'s body till the prenatal development. Ex: Human
5: Gametogenesis refers to the process of production of male and female gametes.
6: The process of production of egg from egg mother cells in females is called as oogenesis.
7: Spermatogenesis is the process of production of sperms from sperm mother cells.
8: The two identical halves of a duplicated chromosome are called as sister chromatids.
9: Pachytene of prophase I of meiosis I
10: Anaphase I
