Interbreeding fails when organisms are sufficiently different, the more closely related they are, the better chance they have. But. And even then, sperm require more than a little boost from the female productive system to make sure they get to the finish line.

What would be an example of a remarkably stretched out interbreeding ? We diverged from our closest extant relative, the chimpanzee, as many as 7 million years ago. That suggests that humans interbred with their primate cousins at some point before the Neanderthals went extinct about 30,000 years ago. But thats not likely to happen, because what the human and dog instructions would really be doing is competing with each other. If a human were indeed inclined and able to impregnate a monkey, post-zygotic mechanisms might result in a miscarriage or sterile offspring. Some pregnant women are allergic to cats, and coming into contact with a cat can trigger an allergic reaction. Immerse the whole thing in a saline solution for a few hours and then flush the sperm back out. Just as each species has a unique genome, each species has a certain number of chromosomes. False! Even the first step is a struggle. Each species has a genome that is unique, which is why people are people and dogs are dogs. Here are twelve of the most common ones. Once inside the Bufo egg, the Rana sperm nuclei went into action, doing what they would usually do inside an egg. Ligers have the ability to mate with other animals.

While its true that semen is composed of ingredients like vitamin C, zinc, protein compounds, cholesterol and sodium, claiming sperm contributes to your daily nutritional value is false advertising. In fact, most of the motility work is done by the uterus muscles. Researchers havent pinned down exactly which mechanisms prevent interbreeding under most circumstances. This is pretty easy to do in birds. Lets dig into it and see what we can learn. Another disappointing factor was that under every condition, the semen itself wasnt very good. (1984).
