The ability of the animals to survive depends on the number of offspring and not on the size of the animal

Large mammals give birth to a smaller number of offspring in each litter, so the risk of extinction increases. In amphibians, on the other hand, large females actually lay more eggs, so in amphibians it is precisely the smaller animals that are in danger of extinction

A species of hybrid salamanders, all of which are female, have found a genetic formula for success - to mate with many males and use equal parts of each partner's genetic load in their offspring. The research reveals ways in which some animal species - all-female populations of fish, lizards and others - can use their genes to increase their chances of success.
