There are three basic types of mutation - in Q:why is it important for germ cells to be haploid? There are three bones in the human arm: the humerus (upper arm) and the ulna and radius (forearm). Further genetic research has demonstrated that whales may be closely related to hippos. Structures in adult lobsters and crayfish are so similar (homologous) that the same lab instructions can be used for dissecting either, yet the crayfish egg develops directly into the adult form while the lobster egg reaches the homologous pattern through a free-swimming larval stage. Crocodile The humerus is shorter and wider. Homologous limbs can be used for flying, swimming, walking, or everything humans do with their arms.
