What is less metabolically costly to an animal prezygotic or post zygotic isolation?
Prezygotic isolation because it is usually only a result of different mating calls or times. In postzygotic isolation the organism usually dies before it has a chance to reproduce or is infertile.
Which members can interbreed and produce fertile offspring are in the same Kingdom phylum species or family?
Members of the same species can interbreed and produce fertile offspring. For example horses and zebras have been known to mate successfully because they are of the same species.
What animals can mate with different breeds?
Yes. Sometimes this is intentionally set up by humans. Mules, for example, are produced by a cross-species mating between horses and donkeys. Some happen naturally; many species of felids can interbreed if they're close enough in size, and it's fairly common to find crossbreeds of whatever the native small wildcat is with domestic cats. In some places, such as Scotland, this happens so extensively that the true Scottish Wildcat is now quite rare. Even larger felids can interbreed to produce animals such as the liger or tigon (male lion-female tiger and male tiger-female lion, respectively). In many cases, the crossbreeds are infertile (mules, for example, are almost always sterile). However, this is not always true.
Why is it more difficult to estimate heritability in humans than in livestock or laboratory animals?
Heritability is the likelihood of different traits being passed down in a species. It is more difficult to estimate in humans than in livestock or laboratory animals because humans are less controlled. Humans will interbreed among races and cultures, while animals generally keep to their own type.
What is the meaning of physical adaptation?
A "Physical Adaptation" is when the body of the animal changes in response to a change in its environment or is circumstances within its environment - a new competitor for food or and new food source or a new predator. This is obviously different from a "Behavioral Adaptation" were the animal changes the way it dose things because of changes mentioned above. Physical adaptation usually come with associated behavioural adaptations, but behavioural adaptations can develop in isolation. Two animals of the same species can look identical but exhibit different behaviours because they live in slightly different environments.
What are birds that cannot interbreed because they have different mating songs characterized by?
behavioral isolation
The eastern and western meadowlark do not interbreed because they have different what?
Mating songs
A group of organisms that can interbreed is called a?
When a group of organisms can interbreed they are considered a species. Humans can interbreed and produce other humans because they are the same species.
The island sinks and the population of birds that lived on the island returns to its original habitat. what about these bird populations is true?
The populations will not be able to interbreed because they are different species
What is less metabolically costly to an animal prezygotic or post zygotic isolation?
Prezygotic isolation because it is usually only a result of different mating calls or times. In postzygotic isolation the organism usually dies before it has a chance to reproduce or is infertile.

Why were different languages invented?
Language developed from a necessity to communicate with other humans. The reason we have different languages is because they developed separately due to geographic isolation.
Why is liger not a species?
because they only breed in captivity not in the wild. plus they cant interbreed
How do new species form?
The central idea of biological evolution is that all life on Earth shares a common ancestor. Over a large number of years, evolution produces diversity in forms of life due to gene flow, mutations, migration, genetic drift, and natural selection. Some things can be explained, for example, in geographical isolation. Over time a species which can not interbreed because of mountains, becomes less alike and can no longer interbreed to form fertile offspring.
