It is sometimes observed that offspring do not resemble their parents for a particular character, even though the character vari
es in the population. Suppose this were the case for beak depth in the medium ground finch.What would the plot of offspring beak depth against parental beak depth look like?
Sometimes offspring do not resembles their parents because of variation, so these character varies in population. When Darwin went to Galapagos Islands, he observed an amazing diversity of characters. He realized that there were many varieties of finches in the same island. He collected two sets of parent offspring data in two different years. Most of the parents who captured before their beak depth were known then he captured offspring with fledged and measured their beak depth. He calculated average beak depth of two parents and then compared with offspring beak depth.
Squirrels cannot live where it gets too hot or too cold. Physical factors such as temperature, availability of water, or mineral nutrients can limit where particular species can live.
