Phenotype is used to indicate the external or physical appearance of an individual. The sum of the activities of the gene and the impact of the environment on them leads to the formation of visible traits called the phenotype.

Homozygous- It is an organism with identical alleles, e.g., TT, RR, rr, tt. Homozygous individuals are generally genetically pure breed. A homozygous individual produces only one type of gametes.

Heredity is the passing on of traits from parents to their offspring either through asexual reproduction or sexual reproduction. It identifies the characteristics we genetically acquire from our parents and our ancestors.
