Explain what Dawkins means when discussing local rules on the cellular level (both in terms of tissue development and of their internal chemistry).

The development of the embryo is what Dawkins means that is performed by the local rules on the cellular level in terms of internal chemistry and tissue development. A small and local unit present in the human body that follows the rules of the on the particular scale.

Dawkins explains that development that various tissues develop and controls other cellular responses during the development of the embryo is in progress. He also suggested that differentiation of the cells is asymmetric cell division.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
