☆☆☆☆☆The diploid generation in the life cycle of a plant, and that produces haploid spores by meiosis.
A diploid form of a plant
Gene flow is genes moving between two populations.
the transfer of genes from one gene pool to another
two populations transferring genes
Vestigial structures do not harm the organism. Nature selects against only harmful traits.
They are thought to have separate paths of evolutionary development.
They developed along different evolutionary paths.
They had independent evolutionary development.
When there is low gene flow
When there is no selective pressure
When there is a bottleneck
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.
changes in the DNA sequence
Allopatric Speciation (geographic isolation) can lead to the formation of a new species because the population is split in two smaller populations by a physical barrier (river, canyon, mountain...).
it was a land plant.
The proteins in the amino-acids might have been responsible for the change in the hemoglobin between gorillas and humans.
