'
Hal knew from his tone that it was no use asking about themother.
Big tears rolled from Fobo's round blue eyes.
'You won't understand what has happened, Hal, unless you comprehend the lalitha's unique method of reproduction. Three things the lalitha needs to reproduce. One thing must precede the other two. That primary event is to be infected at the age of puberty by another adult lalitha. This infection is needed to transmit genes.'
'Genes?' said Hal. Even in his shock, he could feel interest and amazement at what Fobo was telling him.
'Yes. Since lalitha receive no genes from the human males, they must exchange hereditary material between each other. Yet – they must use man as a means.
'Allow and permit me to elucidate. An adult lalitha has three so-called banks of genes. Two are duplicates of each other's chromosomal stuff.
'The third, I will explain in a moment.
'A lalitha's uterus contains ova, the genes of which are duplicated in the bodies of microscopic wrigglers formed in the giant salivary glands in a lalitha's mouth. These wrigglers – salivary ova – are continually released by the adult.
'The adult lalitha pass genes by means of these invisible creatures; they infect each other as if the carriers of heredity were diseases. They cannot escape it; a kiss, a sneeze, a touch, will do it.
'Preadolescent lalitha, however, seem to have a natural immunity against being infected by these wrigglers.
'The adult lalitha, once infected, then builds up antibodies against reception of salivary ova from a second lalitha.
'Meanwhile, the first wrigglers she is exposed to have made their way through the bloodstream, the intestinal tract, the skin, boring, floating, until they arrive at the uterus of the host.
'There, the salivary ovum unites with the uterine ovum. Fusion of the two produces a zygote. At this point, fertilization is suspended. True, all genetic data needed to produce a new lalitha is provided. All except the genes for the specific features of the face of the baby. This data will be given by the male human lover of the lalitha. Not, however, until the conjunction of two more events.
'These two must occur simultaneously. One is excitation by orgasm. The other is stimulation of the photo-kinetic nerves. One cannot take place without the other. Neither can the last two come about unless the first happens. Apparently, fusion of the two ova causes a chemical change in the lalitha which then makes her capable of orgasm and fully develops the photokinetic nerves.
