REPRODUCTIVE BEHAVIOURS

PERFORMANCE OBJECTIVE

Students should be able to;

  1. Explain courtship
  2. Discuss courtship behaviours in animals

CONTENT

Courtship is a social behaviour in which there is an interaction between the male and female members of a species leading to mating and reproduction. Courtship evolved because a very large number of sperms is produced which must search and fertilise few ova leading to competition among sperms.

 

Since males possess sperms, they must compete with one another to win over the female to fertilise her ova which are a limited resource. The gametic selection has translated into sexual selection among males and females, leading to male-male competition and female choice. Courtship display is an extension of this male-male competition in which males evolved various devices and techniques to persuade the female to reproduce.
