Is a group of individual organisms that can interbreed and produce fertile viable offspring?
According to the most widely used species definition, the biological species concept, a species is a group of organisms that can potentially interbreed, or mate, with one another to produce viable, fertile offspring. In this definition, members of the same species must have the potential to interbreed.
What is it called when species interbreed?
Hybridization: ↑ Breeding between two different species. Species: ↑ Organisms that are similar to each other and can breed together to produce fertile offspring. Not all scientists agree on how to define what separate species are.
What is a group of interbreeding individuals of the same species living in a given area?
A population is defined as a group of individuals of the same species living and interbreeding within a given area. Scientists study a population by examining how individuals in that population interact with each other and how the population as a whole interacts with its environment.
What happens when two species interbreed?
When two different species successfully mate, the resulting offspring is called a hybrid. Such encounters can affect the conservation and evolution of a species. When two different species successfully mate, the resulting offspring is called a hybrid. Hybrids are often, but not always, sterile (think of mules).
Which group of organisms that can produce fertile individual through natural selection?
Explanation: A species is a group of individual organisms that interbreed and produce fertile, viable offspring.
What is the group of organisms that can produce fertile individuals through natural reproduction?
A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.
What is a fertile offspring?
In order to be considered to be a single species in the biological species concept, a group of organisms must produce healthy, fertile offspring when they interbreed. In some case, organisms of different species can mate and produce healthy offspring, but the offspring are infertile, can’t reproduce.
What is a group of interbreeding individuals?
A species is a group of individual organisms that interbreed and produce fertile, viable offspring. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring.
Is a group of individuals that belong to the same species and live in the same area?
Population: A group of organisms of the same species, living in the same area at the same time.
Are hybrid species fertile?
The crossing between plants – or animals – of closely related species can produce offspring that, although of hybrid origin, are fertile, even though some chromosomes do not encounter their respective partner in the initial phases of cell division. Genetic information alone is insufficient to identify fertile hybrids.
Are all hybrids infertile?
Hybrids between closely-related species are often inviable or sterile. Hybrids between closely related species are often inviable or, if they live, they are sterile. This hybrid inviability and sterility, collectively known as hybrid incompatibility, can reduce the exchange of genetic variants between species.
Can two distinct species interbreed with each other?
There is NO criteria that says that two distinct species CAN’T interbreed. Consider the example of wolves, coyotes and dogs: three distinct species that can interbreed.
Can two different species produce the same offspring?
However, if two species actually represent incomplete phases of speciation they may produce offspring, that may be sterile, impaired, or viable. Complete speciation can take millions of years – depending on generational management of that genetic information. Two closely related species under these circumstances could produce viable offspring.
Why do plants produce more fertile hybrids than animals?
Generally, plants seem more capable of producing fertile hybrid offspring between related species than are animals because plants can spontaneously double their chromosomes, and doing so can restore fertility to a previously sterile hybrid.
What is the difference between hominin species interbreeding?
The important point, with respect to interbreeding of species, is that hominin species separated by several million years of divergence can still produce fertile hybrid offspring. By contrast, the divergence time separating erectus from sapiens, or the latter from Neanderthals, is much less.
