For the raw sex appeal of the burlesque "shows" there is no defense, either.These "shows" should be under official supervision, at the least, and boys beneath the age of eighteen forbidden, perhaps, to attend their performance, just as we forbid the sale of liquors to minors.For some fish, the number of males in the population determines the sex of the fish.If there are not enough males, some females become males.
I went to work in university admissions for a certifiable narcissist and left after a year.Clinging to rocks and to each other, they form piles. If another limpet attaches itself on top of the male limpet, the newcomer becomes male, and the male limpet beneath it reverts to being female.These slipper limpets show the evolutionarily advanced feature of internal fertilization, and the male on top extends his reproductive organ down the pile of females below him to fertilize their eggs.When the sex of an organism is determined by the sex chromosomes, males and females are generally produced in equal numbers.In other organisms, such as bees and wasps, in which females develop from fertilized eggs and males develop from unfertilized eggs, distribution of the sexes is unequal.
In other animals sex is often determined by environmental factors and can be a variable phenomenon.
