Principle of segregation-genes occur in pairs in an individual. In the production of sex cells, that pair is separated. Each sex cell contains one gene of the pair. Gene- a segment of dna that codes for a protein. Allele- an alternative form of the same gene. Genotype- set of genes possessed by an individual (e. g. rw) Phenotype- the physical manifestation or expression of the genotype. Homozygous-situation of having two copies of the same allele (e. g. rr and ww)
