1. Define genotype and phenotype‚ and describe how they are related. Genotype is the genetic make-up‚ the inheritable information‚ which comprises an individual organism. It is the code that is copied in reproduction and is passed from 1 generation to the next. It serves as the main guide in the growth‚ development and maintenance of a living organism; it also controls the formation of certain proteins and regulation of metabolism and synthesis. Alleles are alternative forms of a gene and genotype

Group selection describes natural selection operating between groups of organisms‚ rather than between individuals. This would produce adaptations that benefit the group‚ rather than the individual. Darwin’s theory of evolution was based upon individual selection‚ and he rejected the idea of group selection.

If something is living it will carry out all of the seven activities shown opposite. Some non-living things show one or two of the seven characteristics
