2B) Jane is an ant, an organism with a haplo-diploid mating system (females are diploid, males
are haploid). In a parallel of J.B.S. Haldane’s statement, should Jane give up her life to save two
of her sisters? Assume all ants can reproduce and will produce 2 offspring (neither is correct in
reality, but assume it for your calculations). List all of your calculations, and your reasoning on
why you plugged in specific numbers.
Solution
In Hymenoptera, the order of insects that includes the bees, ants having unusual genetic method
of sex determination of sort - haploid male - diploid female is called Haplo-diploid mating
system.
Male : it has mother but no father, male develop from an unfertilized egg, making them haploid
Female: these are diploid - two copies of each chromosome
According to Hamilton rule we calculation relatedness . Under this assumption mother only
mate once, sister are more strongly related to each other than own daughter
gene proportions in haplo-diploid :
Father and Son = 1/2 ; Full Brother = 1/4
Mother and Daughter = 1/2 ; Full sister = 1/4
So according question assumption not possible to reality..
