When two species become so different that they can no longer breed it is called what?
On my worksheet for biology the possible answers for that exact question areinfertilityextinctionisolationselection.hope that narrows it down_____________________________The answer is: isolation.
What are the 3 stages in formation of a new species?
The three stages in the formation of a new species are isolation, divergence, and reproductive isolation. Isolation occurs when a population is separated into two groups, leading to genetic differences. Divergence happens as each group adapts to its environment, resulting in further genetic changes. Finally, reproductive isolation develops when the two groups can no longer interbreed successfully.
When does behavioral isolation occurs?
when two populations are capable of interbreeding but have differences in courtship rituals.
What are the two kinds of reproductive isolation mechanisms that biologists divide?
Temporal isolation-species mating at different times of the year.Behavioral isolation-mating behaviors in two groups of isolated populations change, thus making individuals from the two groups not attracted to each other.Pollinator isolation-some closely related plant species have flowers that attract different pollinators, preventing the two species from inbreeding.Mechanical isolation-when reproductive organs in closely related species change drastically, making it impossible for one species to mate with another.Gametic isolation-when incompatibilities between the sperm and eggs of closely related species keep them from fusing.Hybrid inviability or sterility-when the egg gets fertilized, the resulting offspring may not live (inviable) or it is sterile.
When does geographic isolation occur?
Geographic isolation occurs when a physical barrier, such as a mountain range, river, or body of water, separates a population into two or more distinct groups. This isolation prevents the groups from interbreeding, leading to genetic divergence and potentially the formation of new species over time.
What two nations turned to policies of isolation by the seventeenth century?
China and Japan
What is it called when two species reproduce at different times?
It is called temporal isolation. Temporal isolation is a type of reproductive isolation where two species reproduce at different times, thus preventing them from mating and producing offspring together.
What are the two main types of isolation?
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
2 policies maria therasa had?
There were two policies that Maria Theresa had. The two policies were faithful and policy.
How is speciation and reproductive isolation related?
Reproductive isolation is a type of speciation. Reproductive isolation is when a species divides forming two subspecies, due to different mating periods.
Can one person have two policies on two different cars?
Can one person have two car insurance policies on two different cars
What are the two types of reporting isolation events are observer-reported and media reporting?
FALSE
What is the condition in which two populations cannot interbreed called?
isolation
What situation occurs when members of two different species cannot interbreed and produce fertile off-springs?
Reproductive Isolation.
What is the correct spelling for business's policies?
Business policiesMeaning: the policies of business in generalBusiness's policiesMeaning: the policies of a businessBusinesses' policiesMeaning: the policies of two or more businesses
Can you have 2 life assurance policies?
Yes, you can have two life insurance policies. There are people who have even more than that. It isn't recommended to have a large number of policies, but two is not uncommon.
Two populations kept separate by a river are characterized by?
Geographic isolation
