An accepted theory that chromosomes are the material of inheritance, and that they are associated in paternal-maternal pairings; dervied from the collective work of Boveri, Sutton, and Morgan.

When chromosome pairs randomly align along the ... The outcome of a dihybrid cross illustrates the third and final principle of inheritance, the principal of independent assortment, which states ...

The cell's nucleus contains chromosomes. These are long threads of DNA, which are made up of many genes. Humans have around 25,000 genes across their 23 pairs of chromosomes.

Thomas Hunt Morgan (shown) discovers a white-eyed mutant in his laboratory fruit flies. His continuing work would confirm that genes, the units of heredity, are located on chromosomes.

The study leverages human data from the 1000 Genomes Project combined with mouse models of human X chromosome-linked DNA ...

Chromosomes are located in the nucleus of a cell and can be seen through a microscope ... Many members have been affected generation after generation. The inheritance is not straightforward. Familial ...

Each gene might have different forms, and these are called alleles. The diagram shows the relationship between the cell, its nucleus, chromosomes in the nucleus, and genes.

Cancer cells have special adaptation mechanisms that allow them to proliferate despite changes in their genetic makeup.

Cephalopods may have the oldest sex chromosomes of any animal, according to a new discovery in the octopus genome.

Cancer cells have special adaptation mechanisms that allow them to proliferate despite changes in their genetic makeup.

Most C. elegans are hermaphrodites capable of self-fertilization, typically producing hermaphroditic offspring with two X chromosomes. Males, with their single X chromosome, arise due to errors during ...
