7-8 ‘Sex’ is “determined” by the temperature at which the eggs are raised and this occurs in all crocodiles and alligators, some lizards and turtles, and occasionally in fish. The female can “control” the “sex ratio” amongst her offspring by laying eggs in a sunny or shady area. 5- “Only two genders occur, corresponding to the two sexes”. This also is not true - there are many species that show three or more ‘genders’ with cases of each “sex” occurring in two or more forms. Remember also stereotype number (1) that “the most common body form in plants and, may be, in half of the animals is to be ‘both’ male and female at the same or at different times during its lifetime”. 6- “Males and females look different from one another”. Not true - in some species, females and males are “almost indistinguishable”. In other species, males come in two or more forms, one is similar to a female while the others are different (from a female). 7- “The male has the penis and the female lactates”. This also is not true, in the spotted hynea, ‘females’ have a “penislike” which is externally identical to that of ‘males’. According to Berkowitz (2022), the female spotted hyena’s penis is used for urination, mating, and also giving birth. In the fruit bat of Malaysia and Borneo, males have “milk-producing mammary glands”.
