Let me write about the Fisherian runaway process. This is a process whereby sexual selection occurs when either a male has a trait that gives it advantage over another male, or when a female has a preference for a male with that trait. Which ever the reason, this would result in an increase in intensity for that preference. The females who mate with such males, would not only confer the genetic trait to her sons, but also confer the preference for that genetic trait to her daughters. This process would go on until those males not selected for become selected for, I presume this would be when there are changes in the environment; or until the females change their preference and no longer select for males with such trait.
This is my feeble attempt at 15 minutes of writing a day.
Perhaps, I should switch to writing on paper instead as suggested by Wee Foong so that I can simulate exam conditions even more.
