In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendelβs discoveries in genetics. over a century later, darwinβs idea of evolution was modified in order to incorporate mendelβs rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendelβs rules of genetics and darwinβs idea of biological evolution? a.)mendelβs genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendelβs theory of genetics.c.)mendelβs genetics replaced darwinβs entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
