(molecular biology) A complex formed by joining two complementary strands of nucleic acids.

adjective

Of or pertaining to the offspring produced from crossbreeding.


Supplement

(biology): For instance, a mule is an animal produced by breeding animals of different breeds, particularly a cross between a horse and a donkey. Different types of hybrids:
*Single cross hybrid – first generation of offspring resulting from a cross between pure bred parents
*Double cross hybrid - offspring resulting from a cross between two hybrids of single cross
*Three-way cross hybrid – offspring from a cross between a single cross hybrid and an inbred line
*Triple cross hybrid - offspring resulting from the crossing of two different three-way cross hybrids
*Population hybrid – offspring resulting from the crossing of plants or animals in a population with another population. For instance, a cross between difference races

Human Gamete Compatibility Going Backwards

... a new organism (whether it's going to be a hoof or a hand). Unless there is a serious clash between the two organisms that cannot be reconciled, a hybrid will be born. This hybrid will not breed true and can only be considered a first step toward the creation on new species...

Re: Speciation challenges the meaning of "beneficial mutation"

Are there any problems with the concepts I have put forth? Yes. It's not "unable to produce viable hybrids", but rather "reproductively isolated". Meaning that their hybrid offspring is sterile (like mule); or that they are geographically isolated and, ...
