Morganism

Morganism is a theory that was created at the beginning of the 20th century by the American scientist Thomas Morgan and his colleagues. The theory assumed the existence of genes that are inherited and their influence on the phenotype of the organism. Morganism was based on the idea that genes are located on chromosomes located in the cell nucleus. Genes are hereditary characteristics that determine the physical characteristics of an organism, such as eye color, hair shape, height, etc.

One of the key principles of Morganism theory was the idea of ​​a linear arrangement of genes on a chromosome, called the linear theory of heredity. However, this idea was refuted by geneticists in the 1930s. Geneticists have discovered that genetic traits are not transmitted in a straight line, as assumed by the linear theory of heredity, but are encoded by a group of genes called loci. But despite the fact that the linear theory of Morganism was refuted, many of the ideas and principles of Morganism have been preserved and are used to this day.

So, Morganim's theory was based on ideas about genes, their linear arrangement
