Flipper of whale and wing of bird has similar morphology and anatomy, but differ in their functions according to their species as well as the habitat where they live in.
A dolphin’s flipper, bird’s wing, cat’s leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.

During meiosis I, how could you have arranged the chromosomes in a different way? How do the differences affect the end result of meiosis??
Explanation:
Meiosis is the formation of reproductive cells, like the egg in the fallopian tube; if not fertilized by sperm, it is expelled by the menstrual cycle.
Some conditions during fertilization can be disrupted by an egg attaching to the fallopian tube instead of the uterus causing an ectopic pregnancy. Arranging chromosomes in a different way causes congenital defects like color blindness, crohn's disease down's syndrome, etc.
