Right from the early days of human civilization man has been breeding selected species that are useful to him. This has produced different varieties of plants and animals. The Result of Selective Breeding..

. Polyploidy may be caused by fertilization of an egg by more than one sperm failure of meiosis during gamete formation. Polyploidy can artificially be introduced by a chemical called colchicine or by crossing diploids with tetraploids. Although triploids exhibit sterility, polyploidy is useful in ..

) which is activated to grow into separate organism by suitable mixture of cytokinins and auxins. The success in tissue culture depends upon a) the precision and length of asceptic condition b) source of explants c) compositions and concentrations of nutrients media d) time and dosage of hormones s..

It is a cross involving two pairs of contrasting characters. For this experiments on dihybrid inheritance. Mendel selected the contrasting characters in the seed coat and cotyledons. He conducted a cross pollination between a pure breeding plant with round seed coat and ye..

Selection is an important technique in plant breeding. It involves picking the healthiest and the best ones out of the entire crop and reproducing them under controlled condition..

Much before the advent of modern biotechnology, there were several practices that were commonly followed. Breeding (hybridisation) of plants and animals to change the genotype and phenotype of the hybrids is probably the oldest and the most widely used technique of genetic engin..
