Answer: No, because evolution can also produce new traits on a species without changing it. Lizards in an area where the surface is slicker, may develop stickier feet in order to stay rooted to their surfaces easier. Some mice become immune to poison, and some bacteria and germs that are often vaccinated for become immune to those vaccinations and can get past those barriers.

Independent assortment
Explanation;
According to the law of independent assortment; During meiosis homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other.
This process results to the formation of gametes that have a unique combination of chromosomes.
By knowing which genes predispose people to particular conditions, doctors will be able to predict which people are likely to suffer from a particular disease and offer a preventive course of action, which may involve medical treatment or lifestyle changes. Furthermore, cures could be found for genetic diseases like cystic fibrosis or sickle cell anaemia. People could be diagnosed with illnesses that they are suspectible to develop in the future and spend their life worrying about it even before they get it.
Question: If they aren't hermaphrodites, can they still be male and female at the same time?
Facts: Different snails reproduce differently, but most snails are "hermaphrodites." Being a hermaphrodite means that any given snail can be both male and female at the same time. This can make it a lot easier for snails to reproduce and quickly make a whole lot of snails! Some hermaphrodite snails do not need another snail to reproduce, but can make more snails all by themselves (this is called asexual reproduction). Other snails are hermaphrodites but still need another snail to reproduce (this is called sexual reproduction). There are also some snails that aren't hermaphrodites, but are either male or female, and must find a snail of the opposite sex to breed with.
