What occurs when formerly interbreeding organisms are prevented from producing fertile offspring?
Reproductive isolation
What is natural selection and what are the assumptions associated with it?
Natural selection is the non-random differential reproductive success of variant traits. The assumptions it rests upon are: - That life reproduces with variation in inherited traits. - That a population always produces slightly more offspring than can comfortably subsist in its niche. - That offspring therefore, directly or indirectly, compete for resources and mating opportunities. - That differences in inherited traits affect the average number of fertile offspring raised by individuals. - That traits that allow their bearers to raise a higher average number of fertile offspring spread throughout the population faster than rival traits.
What does fertile offspring mean?
Fertile offspring are offspring of parents which can continue to reproduce (for example Humans). However you can also get infertile offspring which cannot reproduce (an example of this is a mule, but it is not always the case.
What is a group of similar organisms that interbreed in nature?
If a group of organisms cannot be interbreed, and create fertile offspring, thent hey are separate species. If the can be interbreed, and the offspring can also interbreed, then they are different sub-species, or phases of the same species.
A group of organisms whose members successfully reproduce among themselves is a called a?
A population of organisms that can reproduce fertile offspring is called as species
What is an interbreeding population that produces healthy fertile offspring?
Macartney?
WHAT can occur only when either interbreeding or the production of fertile offspring is prevented among members of a population?
speciation
What occurs when formerly interbreeding organisms are prevented from producing fertile offspring?
Reproductive isolation
What is the species?
A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring
A group of organisms capable of interbreeding and producing fertile offspring is known as?
Species
3 things needed to be a species?
A species is a group of organisms that have the capacity of interbreeding and producing fertile offspring.
What occurs when forerly interbreeding organisms are prevented from producing fertile offspring?
If the species is prevented from producing fertile offspring - the species will eventually become extinct.
What is an animal species?
An animal species is a group of organisms with similar physical characteristics that can interbreed and produce fertile offspring. Members of the same species share a common gene pool and can mate to produce offspring that can also reproduce.
What is a group of organisms that can interbreed and produce fertile offspring in nature?
population
What do you call a group of of organisms that can mate and produce fertile offspring?
population
What is a population of organisms that an breed with each other and produce fertile offspring?
A species.
What terms refers to one or more populations whose members are capable of interbreeding?
If animals can breed and produce a viable (fertile) offspring they are termed a "species". Often two closely related species can inter-breed and produce an offspring that will be a non-viable (sterile) hybrid. An example of the later would be the cross-breeding of a horse with a donkey.This cross produces a "Mule", which is sterile & unable to reproduce.
