| |
Heidi Parker, Ph.D.: The DNA in all animals is the same kind, it is made of the same components and, for the most part, codes for the same genes. There are changes in the sequences, in the order of the genes, in the size and composition of the chromosomes and in a few speicific genes that allow you tell the organisms apart. |
