Cotton refers to those species of genus Gossypium that bears the spinnable seed coat fibres. The proteins and enzymes
are the primary product of the genes and hence are most suitable for determination of genetic purity and polymorphism. The
biochemical and molecular markers may complement the efforts to reduce the burden to a greater extent, as these are estimates
devoid of environmental factor which a cause of error. Especially in the selection of parents based on biochemical and
molecular polymorphism, there is marked improvement in the screens for the quantitative traits and understanding their
architecture.
