Henry was studying two populations of the same species of lizards One population lived on an island and the other lived on
the mainland. Both populations were affected by a hurricane that hit the island and the mainland with equal force A year later,
Henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland
species. Which best deschbes a conclusion he might have reached?
O Gene flow greatly affects small populations, but large populations can recover
O Genetic drift greatly affects small populations, but large populations can recover
O Gene flow greatly affects large populations, but small populations can recover
Genetic drift greatly affects large populations, but small populations can recover

osteogenesis imperfecta (oi) refers to a congenital ailment of bones. in the condition, the bones become brittle or fragile. this ailment is a general result of the defect or mutations in the genes (colia1 or colia2). this mutation results in imperfect collagen formation either in quantity or quality wise.
