... answer is found in the cell nucleus. Each kind of organism has a specific number of chromosomes. For example, every body cell of a fruit fly has 8 chromosomes (4 pairs); a human has 46 (23 pairs); a garden pea has 14 (7 pairs). Along each chromosome there are many dark bands. Each band is a small pa ...

Genome evolution
Genome evolution is the process by which a genome changes in structure (sequence) or size over time. The study of genome evolution involves multiple fields such as structural analysis of the genome, the study of genomic parasites, gene and ancient genome duplications, polyploidy, and comparative genomics. Genome evolution is a constantly changing and evolving field due to the steadily growing number of sequenced genomes, both prokaryotic and eukaryotic, available to the scientific community and the public at large.
