Explanation:
Due to the prevalence of malaria in Africa, the allele for sickle cell anemia (HbS) provides a selective advantage. That's why it remains in the population.
A normal African person (HbAHbA), with normal haemoglobin, will not die of anemia, but will die of malaria.
An African person with sickle cell anemia (HbSHbS), with abnormal haemoglobin, will die of anemia.
A heterozygous African person (HbAHbS), with half of his red blood cells (RBCs) being normal and the other half being sickle-shaped, will neither die from anemia, nor malaria since the plasmodium will be incapable of completing its life cycle in the abnormal RBCs.
Thus heterozygous African people will grow, reproduce and pass on the HbS allele to the next generations.
Boiga irregularis or brown snake is a slender, climbing snake with a vertical pupil and large eyes, providing it better nocturnal vision. The species has no natural predator. When the brown snake is accidentally released into the island, it will result in local extinction of the majority of the island's native lizard and bird species.
It will also result in cascading ecological influences by eradicating native pollinators, resulting in the corresponding reduction of the native plant species.
Hence, the correct answer will be fewer birds and more snakes.
