Answer:
Parallel Evolution
Explanation:
It is because only three members are normal while one of them has a rare recessive allele. Due to parallel evolution, the recessive allele will now become common as the other previously distinguished dominant alleles and now all the traits will be in a uniform equilibrium according to Hardy-Weinberg Theorem.
The classical astronomers concluded that heavens were made up of a sphere, because heavens were thought to be perfect and spheres (circles) are a perfect shape. It was Plato who argued that geometrical figures were spheres and everyone agreed to him. It was also believed that the perfect motion of spheres was a uniform circular rotation.
