☆☆☆☆☆a species can gradually change into new species
Gene flow is genes moving between two populations.
the transfer of genes from one gene pool to another
two populations transferring genes
Emigration is the act of moving out of a country.
It is distinguished from Immigration that is the act of moving into a new country.
There must be genetic variation in the population
The system must not be in hardy-weinberg equilibrium.
resources must be limited in the ecosystem
When there is low gene flow
When there is no selective pressure
When there is a bottleneck
It makes the ecosystem more diverse.
Natural selection occurs when four conditions are met:
1. There is variation among individuals.
2. That variation is at least partially heritable.
3. That variation is linked to differential reproductive success.
4. More individuals are born than can survive and reproduce.
Why do organisms in different places have different traits (apex)
allele frequency change Apex :)
The method an organism uses to produce offspring
the way that a species creates offspring
Finches developed many different adaptations. For example, one type of finch had a short strong beak meant for cracking seeds, while another had a long narrow beak for gathering food from the inside of flowers, and cacti, therefore making each species more adapted to its specific environment and more able to gather food then they would on another island with a different main food source.
You mama
The allele frequency does not change.
Which statement is ture about all adaptations
It may be 41.
Organisms are born with them
