Conspecific. Two or more individual organisms, populations, or taxa are conspecific if they belong to the same species. Where different species can interbreed and their gametes compete, the conspecific gametes take precedence over heterospecific gametes. This is known as conspecific sperm precedence, or conspecific pollen precedence in plants. Heterospecific The antonym of conspecificity is the term heterospecificity: two individuals are heterospecific if they are considered to belong to different biological species.

The blood will rush from your feet to your head, keeping oxygen flowing to your brain. Lying down can also help prevent head injuries from falling down when you faint. When to Worry.
