PPT-Heredity and Function

Heredity and Function We have looked at genetics We have identified plants and animals using their structures Now we will look at how genetics and function can effect adaptations Heredity and Function.

Reproduction is characteristic of living things and is essential for the survival of species. . B. Genetic information is passed from generation to generation by DNA; DNA controls the traits of an organism. . What did Mendel Observe?. How do alleles affect inheritance?. Heredity.

Heredity is the cause of similarities between individuals. This is the reason that brothers and sisters with the same parents resemble each other and with their parents. Variation is the cause of differences who do resemble each other are still unique individuals. Thus, we have no trouble in recognizing the differences between sisters, for example, and even ‘identical’ twins are recognized as distinctive individuals by their parents and close friends. .
