Chromosome
A chromosome is a packaged and organized structure containing most of the DNA of a living organism. It is not usually found on its own, but rather is complexed with many structural proteins called his...

Humans Inherited The Tendency For Violence, But Civilization Has Tamed It
As a species, humans seem to have inherited murderous traits via evolution and genetics, but civilization has tamed some of it out, a new study suggests. Scientists in Spain calculated the rate at whi...
Genome
In modern molecular biology and genetics, the genome is the genetic material of an organism. It is encoded either in DNA or, for RNA viruses, in RNA. The genome includes both the genes and the non-cod...

Karyotype
A karyotype (from Greek κάρυον karyon, "kernel, seed or nucleus", and τύπος typos, "general form") is the number and appearance of chromosomes in the nucleus of a eukaryotic cell. The term is also use...

Ploidy
Ploidy is the number of sets of chromosomes in a cell. Normally a gamete (sperm or egg) carries a full set of chromosomes that includes a single copy of each chromosome, as aneuploidy generally leads ...
Autosome
An autosome is a chromosome that is not an allosome (i.e., not a sex chromosome). Autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cell, whereas mem...

Allosome
An allosome is a sex chromosome that differs from an ordinary autosome in form, size, and behavior. The human sex chromosomes are a typical pair of allosomes. These chromosomes determine the sex of an...
Microchromosome
A microchromosome is a type of very small chromosome which is a typical component of the karyotype of birds, some reptiles, fish, and amphibians; they tend to be absent in mammals. They are less than ...
