The native species will more than likely be eradicated or they might learn to co-habitate.
Explanation:
The nonnative bird species will compete for resources with other species that share the same resource. Depending on the stronger animal or the bird that is more fit for that area to survive, depends on whether the native species will be effected or the nonnative species will be affected. If the invasive species has more tools to enhance their survival, then they will likely eradicate the native species. the same can be said for the Native species.
The most likely effect will be a reduction of reproduction and survival in native species.
Explanation:
Since the invasive species did not co-evolve with the native species they will lack natural controls and predators causing increased competition for resources needed by native species. The lack of natural controls and predators not only make the invasive species more prone to consuming more resources they also consume them more effectively leading to an unbalance in the ecosytsem and less available resources for the native species. If resources are not readily available for the native species they can not reproduce effectively making it difficult for them to survive reducing the amount of native species while the invasive species consumes most of the resources and thrives.
Polygenic inheritance is determined by multiple Genes located at different loci on different chromosomes.
Polygenic inheritance happens when an individual posses quantitative traits that become a variation compared to the parent's traits.
This phenomenon happens due to the combination of two or more genes that resulted in the characteristics that considered as the combination of both parents' characteristic.
I think there is more oxygen in the troposphere because the closer you get to earth, the more oxygen there is. The troposphere is very close to the earth, therefore, there is lots of oxygen in the troposphere.
