- b All the genetic information within an organism/cell.
- c Characteristic in which the allele responsible is only expressed in the phenotype if there is no dominant allele present.
- d A mutation that even though it may change a coding sequence exerts no harmful or beneficial effects.

5 True/False questions
Homeotic selector genes → Variation introduced due to the random orientation and subsequent segregation of maternal and paternal chromosomes during meiosis 1, or sister chromatids at meiosis 2.
Phagocytosis → Programmed cell death. An orderly process by which cells self-destruct in an orderly fashion after a certain number of cell divisions, or if they cannot repair DNA damage.
Polyploid → Eukaryotic organisms or cell with more than two sets of chromosomes.
Genetic code → Structure formed on the centromere that attaches the chromosomes to the spindle fibres during mitosis and meiosis.
Codon → A sequence of three bases that codes for a single amino acid according to the genetic code.
