What is referred to as the complete set of genetic material in an organism's chromosomes?

The complete set of genetic material in an organism's chromosomes is referred to as the genome. This term encompasses all of an organism’s DNA, including both the genes that code for proteins and the non-coding sequences. The genome contains the information needed for the growth, development, reproduction, and functioning of an organism.

In contrast, the concept of the phenome refers to the complete set of observable traits or characteristics of an organism, which are influenced by both the genome and environmental factors. Chromosomes are the structures within cells that organize and store DNA but do not represent the entirety of genetic material on their own. The genotype refers specifically to the genetic makeup of an organism regarding a particular trait or traits, representing the alleles inherited from its parents, but does not encompass the complete genetic material in the same way that the genome does. Thus, the term genome is the most encompassing and accurate description of the organism's genetic content.
