Base isolated population is 1000 females. Each is one is on average 25 and lives to be 100 years old and gives birth to three kids...sperm banks so there are no men in the first generation population. 2nd generation is 50%male and 50% female and each female grows up and has three kids. Everyone lives to 100 (for the sake of simplicity) this repeats for 1000 years so what is the population at the turn of each century assuming a new generation happens every 25 years? This is not for school I made this question up for myself but I'm incapable of anything beyond basic arithmetic please help this has been nagging me for months and I can't get Excell to work.
