Somaclones are the genetically identical plants produced by using the somatic cells or the vegetative parts of the plants through the tissue culture technique. Somaclones are the plants that are produced through tissue culture and are genetically identical to the parent plant from which they are produced and cultured. Somaclones are produced through micro-propagation or tissue culture. They are genetically identical to the parent plant, e.g., apple, tomato or banana. Somatic hybrids: These are produced by fusion of protoplast of two different plants. They are genetically dissimilar e.g., Pomato (hybrid of potato and tomato).

- Mendel’s most important discovery is his law of segregation. Segregation is the essence of Mendelism and a fundamental rule of genetics.
- The law of independent assortment holds good only for genes present in different homologous pairs of chromosomes.
- Inheritance of genes, present in the same homologous pair of chromosomes, is governed by the phenomenon of linkage and crossing–over.
- Genes present in the *** chromosomes obey the rules of ***-linked inheritance.

Bio magnification refers to the increase in concentration of the toxic waste at successive tropic levels. Bio magnifications of DDT in an aquatic food chain causes the increase in concentration of DDT at successive tropic levels. High concentrations of DDT disturb calcium metabolism in birds, which causes thinning of eggshell and their premature breaking, eventually causing decline in bird populations.
