noun, plural: fetuses

The yet-to-be born mammalian offspring following the embryonic stage, and is still going through further development prior to birth


Following the embryonic stage, the developing young enters the fetal period, which is in the later stages of development prior to birth. The fetal period is when the offspring has taken a recognizable form as its own species. The fetus is also characterized to possess the major organs in contrast to an embryo. Tthe fetal organs though are not yet fully functional and are still undergoing further development.

In humans, the embryo is called a fetus at the ninth week from the time of conception up to the moment of birth. After being born, the offspring is called an infant or a newborn.

Word origin: Latin fetus (offspring, brood)

Gender divison in two opposites is greatest mistake of manki

... justification of misogyny at work here. There are some "extra" genes at work, but they are mostly receptors that alter development in a fetus and control reproduction. The "quantity" is true, but fairly pointless.

Hereditary Diseases - How to get rid of them?

... bunch of cells. Since ever you have two and more cells you face the same problem as when trying to repair cells in grown man. Of course with the fetus it would be sort of easier (let's say the spread during growth would be bigger), but on the other hand you'd had problem with the mother.
