Boveri–Sutton chromosome theory

The Boveri–Sutton chromosome theory (also known as the chromosome theory of inheritance or the Sutton–Boveri theory) is a fundamental unifying theory of genetics which identifies chromosomes as the carriers of genetic material. It correctly explains the mechanism underlying the laws of Mendelian inheritance by identifying chromosomes with the paired factors (particles) required by Mendel's laws. It also states that chromosomes are linear structures with genes located at specific sites called loci along them.2. The process of synapsis (pseudo-reduction) consists in the union in pairs of the homologous members (i. e., those that correspond in size) of the two series.3. The first post-synaptic or maturation mitosis is equational and hence results in no chromosomic differentiation.4. The second post-synaptic division is a reducing division, resulting in the separation of the chromosomes which have conjugated in synapsis, and their relegation to different germ-cells.5. The chromosomes retain a morphological individuality throughout the various cell-divisions.W. S.
