Cats can have a trait where their ear folds down, a breed called the “Scottish Fold,” displays this phenotype in most breedings The gene for folded ears is dominant (E) and the gene for straight ears (e) is recessive. Write the three genotypes that are possible (choose your letters) and describe their phenotypes. Remember, genotypes have two letters and the phenotype describes what the cat looks like (folded or straight).

Ry 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 describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
