Scientists who studies wildlife in and around the great lakes area found their results to be disturbing.a large number of birds were born with partially developed eyes,crossed bills and webbed feet.what can infer is the reason?

Some key reasons for partially developed offspring:

• Genetic issues, parents sexual organs incorrectly formed, in turn malforming the offspring

• Pollution, parents consuming something they shouldn't have while the offspring was developing

• Breeding between relations; accidently mating with a brother or sister, in turn causing defects as many of the genes are the same
