When a species overproduces it makes it less likely for members of the same species to survive.
The way a species produces offspring
If two different species reproduce and have children, then these children will not be fertile. E.g, when a horse and donkey reproduce together, then the offspring is called a mule. The mule will always be infertile, as will the offspring produced by cross-breeding of species. If two different breeds reproduce, then the offspring should share the characteristics from both breeds.
Members of a group that can interbreed and produce fertile offspring are in the same? it is known as a species
If it were possible - The new offspring would be classified under the male 'parent' animals bloodline.
hybrids
no
Overproduction is a driving force in natural selection, as it can lead to adaptation and variations in a species. Darwin argued that all species overproduce, since they have more offspring than can realistically reach reproductive age, based on the resources available. -Google More offspring are produced than can survive. -gradpoint/novanet
Because the survival rate of the offspring is usually quite low.
they become over populated and the population declines
they become over populated and the population declines
The way a species produces offspring
A group of organisms that can mate and produce offspring which can themselves mate is called a species.
It is possible for any species to breed to any other species. whether or not conception happens is a whole other question. so yes a pine marten can breed with a fox, no offspring will be produced. just like a human could breed with a lowland gorilla, no offspring will be produced.
the average offspring of a bear is 2. But the offspring depends on the species.
If the two species are even able to produce offspring, then the offspring would be a hybrid. For example, a donkey and a horse breed to make a mule. Due to the definition of "species," the offspring would either be infertile, inviable or both.
They are mealworms. They are the offspring of the adult beetles.
Answer 1One species can evolve from two species if the two bypass the barriers between them. These barriers can be physical. For example, mountains or if they are similar in type. A plant can not breed with a human, there are too many genetic differences. If their offspring can interbreed or have offspring of their own they can form a new species. Horses and donkeys are close in genetic type but their offspring are mules and they are infertile and can not have offspring of their own.Answer 2As noted above, a new species may emerge from a hybridisation between two closely related existing species. This is not seen very often in the more complex animals, but happens frequently in plants and may occasionally occur in insects or even birds.
