a genome is a haploid set of chromosomes of an organism, for example in humans who have 46 chromosomes in a diploid set as in two of the same kind of chromosome,1 paternal and one maternal the genome is a single set of 22+X+Y.in a haploid organism the entire chromosome set is its genome.

In biology the genome of an organism is its whole hereditary information and is encoded in the DNA (or, for some viruses, RNA). This includes both the genes and the non-coding sequences of the DNA. The term was coined in 1920 by Hans Winkler, Professor of Botany at the University of Hamburg, Germany, as a portmanteau of the words gene and chromosome.
Most biological entities more complex than a virus sometimes or always carry additional genetic material besides that which resides in their chromosomes. In some contexts, such as sequencing the genome of a pathogenic microbe, "genome" is meant to include this auxiliary material, which is carried in plasmids. In such circumstances then, "genomeey" describes all of the genes and non-coding DNA that have the potential to be present.
In vertebrates such as sheep and other various animals however, "genome" carries the typical connotation of only chromosomal DNA. So although human mitochondria contain genes, these genes are not considered part of the genome. In fact, mitochondria are sometimes said to have their own genome, often referred to as the "mitochondrial genome".

Every living organism has a genome. A genome is the complete set of chromosomes for a particular organism. For humans, that's 23 pairs (46 total) of chromosomes, and it's different for all organisms--camels have 35 pairs, fruit flies have 4 pairs.
