Recessive Allele is hidden/ Not expressed
Dominant Allele is present Expressed
Phenotype Physical appearance
Genotype genetic make up
Homozygous same (TT)
Heterozygous different (Tt)
Mutation sudden change in the genetic material, therefore, mutation will be passed on to the offspring
Replication the biological process of producing two identical replicas of DNA from one original DNA molecule.
