Why do geneticists find that human genetics are rather hard to study, when compared to experimental organisms such as pea plants or fruit flies?
What will be an ideal response?
Humans do not mate randomly (often persons of a particular racial background, height, or other physical characteristic tend to mate preferentially); we have small numbers of offspring that make statistical analysis difficult; we live as long as the geneticist; and often only a few generations are alive to be studied.
