It would be negatively impacted because a foreign species would start to take over a native species’ role in the ecosystem and may also directly (if it’s a predator) or indirectly lead to the decline of other species. So as some species may start to decline and eventually become extinct in that particular ecosystem, the biodiversity level would lessen cuz there’s less types of plants and animals. Less plants and animals could lead to the ecosystem to eventually collapse and it would be literally a mass extinction.
Answer:
Sickle cell anemia refers to a recessive inheritance disorder, in which every individual carries two copies of a gene. In normal individuals, both the copies of the globin gene are normal, and they generate 2 and 4 kb fragments of DNA on digestion by BseR1. A patient with sickle cell anemia is homozygous for the recessive gene and exhibits a mutation in both the copies of a globin gene.
Therefore, BseR1 could not digest the globin gene and generate a single 6Kb fragment of DNA. In a patient acting as a carrier, one copy of a globin gene is mutated and the other is normal. As a consequence, BseR1 digestion generates 6kb of the fragment of DNA (mutated copy) and 4 and 2 kb from the normal copy of a gene.
