In this example, from your text, positive assortative mating is 100% (i.e. there is no random mating). Note that the frequency of heterozygotes is cut in half each generation. Does this match your answers above? Look at the actual values make sure you understand why positive assortative mating leads to an increase in homozygosity.

- What, if anything, does this experiment indicate about the validity of the pangenesis and the germ-plasm theoriesarrow_forwardBecause the reproductive success of female Hanuman langurs (Semnopithecus entellus) is almost certainly lowered when a newly installed male kills their young infants, selection should favor countermeasures against infanticidal males. In this light, why might already pregnant females mate with a new male soon after a takeover even though they are not ovulating? What significance do you attach to the discovery that when mares are impregnated by stallions at stables away from their home locations, they will also copulate repeatedly with the males in their home stables upon their return?arrow_forwardwe discuss various mechanisms of sex determination, including the XX/XY system of placental mammals, and the ZZ/ZW system of birds. Monotremes, the most primitive mammals, have a very intriguing sex determination scheme that shares elements of both of these systems. Please use the internet to learn more about how sex in monotremes is determined. Then write a short essay (300-400 words) describing this system and comparing/contrasting it to the XX/XY and ZZ/ZW systems.arrow_forward
