ANSWER:
The statement is True. Genes are "segments of DNA" and help in determining the phenotype of an individual.
EXPLANATION:
- Phenotype or the physical features and behaviour of organisms are determined by their genes.
- Genes as segments of DNA contain "codes" for the production of "proteins" that determine the various characteristics of an individual.
- Genes are located on chromosomes and can exist in different forms. Gene is considered to be the "basic unit of heredity" and determines the characteristics that pass from parents to the offspring.
