WebChromosome. Chromosomes are the genetic material present in all cells. They are present in the nucleus of a eukaryotic cell. They are a thread-like structure. Each chromosome of a eukaryotic cell contains DNA and associated proteins, known as histone proteins. They are responsible for the hereditary traits and passed from parents to … WebChromosomes. Each species has its own characteristic number of chromosomes. Humans, for instance, have 46 chromosomes in a typical body cell (somatic cell), while dogs have 78 ^1 1. Like many species of animals and plants, humans are diploid ( 2n ), meaning that most of their chromosomes come in matched sets known as homologous …
