Genetics
Point mutations involve minor changes in the genetic material, often single base-pair substitution. Sickle-cell anaemia is genetically determined disorder, caused by homozygosity, producing a single amino acid substitution in the b-chain of the normal haemoglobin molecule.

The morphological expression of the genotype is called the phenotype.
The sum total of the genetic material inherited by an individual is called genotype.
The bond or the link formed between the carboxyl group of one amino acid and the amino group of another amino acid with the elimination of a water molecule is called a peptide link.
