the answer is SPECIES BECAUSE the common definition is that of a group of organisms capable of interbreeding and producing fertile offspring of both genders, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology.
What else can I help you with?
What refers to a group of populations living in a given area?
Several groups of populations in an area/habitat is called a community.
What is the least common race?
In the context of ethnicity, Pacific Islanders and indigenous populations tend to be the least common race globally. These groups often have smaller populations compared to other racial groups and are less prevalent in many countries.
In which area would a population be geographically isolated?
A population would be geographically isolated in areas such as islands, mountaintops, or remote valleys where physical barriers like oceans, mountains, or deserts prevent easy gene flow with other populations.
What is one cause of speciation?
One cause of speciation is reproductive isolation or the separation of the population of a species from other populations so that it can change without keep getting mixed with other populations( and therefore becoming identical to other populations).
What happen when organisms populate a new area and are isolated geographically from other populations of the same species?
Isolated populations can undergo genetic divergence over time due to genetic drift and natural selection. This can result in the accumulation of unique genetic variations, potentially leading to the formation of new species through the process of speciation. Over generations, the isolated population may evolve different characteristics and adaptations compared to the original population.
What are groups of reproducing populations that are isolated from other groups?
These groups are called "reproductive isolates," and they play a key role in the process of speciation by preventing gene flow between populations. Reproductive isolates can result from factors such as geographic barriers, behavioral differences, or genetic incompatibilities.
Which idea explains Darwin's observations about galapagos Islands finches?
Biological Species Concept, which defines species as groups of interbreeding populations that are reproductively isolated from other groups.
Which best describes the biological species concept Genetic exchange does not occur between reproductively isolated populations. Sexually reproducing species inhabit particular niches. Certain factors?
The biological species concept defines species as groups of individuals that can interbreed and produce fertile offspring, with genetic exchange occurring within these populations. Reproductively isolated populations, on the other hand, do not exchange genes, leading to distinct species over time. This concept emphasizes the importance of reproductive isolation and genetic continuity within species while recognizing that factors such as ecological niches can influence their evolution and diversification.
Do horned toads live in groups or alone?
Amphibians are not herd animals. Toads and other amphibians live alone except when they are reproducing.
What is reproduction species?
Species are community of populations that are reproductive isolated from other and that occupy a specific niche. Such sister species can live in sympathry.
What is believed to be the dominant mode of speciation among most groups of organisms?
The dominant mode of speciation among most groups of organisms is allopatric speciation. This occurs when populations of a species become geographically isolated from each other and over time, genetic and environmental differences accumulate, leading to the formation of distinct species.
What happens when a population is isolated into two or three groups?
Actually, nothing happens. But if the distances increase between the groups, then they become geographically diverse and hence there will be a greater chance of development of a new species from the isolated groups. Other factors also influence this, like the presence of already existing populations in the new area.
If a population becomes isolate from other populations of the same species and then genetic divergence occurs that prevents them from breeding with other populations what is it called?
This is called allopatric speciation, where a population becomes isolated and evolves separately, leading to genetic differences that result in reproductive isolation from other populations of the same species.
What is reproductive species concepts?
Species are community of populations that are reproductive isolated from other and that occupy a specific niche. Such sister species can live in sympathry.
What three types of barriers that can cause populations to become reproductively isolated from each other?
Isolation can be due to behavioral, geographical, or temporal barriers.
Can two groups become different species if they are not reproductively isolated from each other?
Yes. As an example, a species may come in two varieties that differ in appearance. Many animals prefer to mate with individuals that resemble them. Sexual selection can therefore cause two populations to diverge.
What refers to a group of populations living in a given area?
Several groups of populations in an area/habitat is called a community.
