Why not hundreds of different sexes, why only two ?

... started with some reciprocal exchange of genetic material between similar individuals. But later organisms had to deal with the problem of inbreeding depression. As a result of this, a mechanism that ensures that sexual reproduction occurs only between unrelated cells, was evolved. In essence, ...

Re: Uses for the PCR technique?

... in different animals of the same species to determine if they are related as well as what animals would be good to mate together to prevent inbreeding in captive animal populations… you could also go with using PCR to unlock which DNA sequences do stuff in the cell but you would have to ...

Conditions for a stable ecosystem? (for a simulation)

... It might still be interesting to set the appropriate chances of certain types of mutations (deleterious) in certain types of reproduction events (inbreeding, mitosis?) but I don't know much about that. Weather: I also thought about this as a fun extra. When I thought of plants I thought of seasons, ...

Re: Human Evolution and one race

Mith: thanks for the scientific explanation on "inbreeding" mcar: It makes sense that homozygosity increases due to inbreeding, but with the "one race" theory, would it really be inbreeding? Take for example china. It's population ...

Human Evolution and one race

In the case of inbreeding, the chances of homozygosity increases. Most of our deleterious genes are usually expressed when they pair in such a way. Variation is said to be so important in developing many strategic and evolutionary ...
