    Nuclear transfer, the introduction of the nucleus from a cell into an enucleated egg cell (an egg cell that has had its own nucleus removed). The nucleus is the heart of the egg cell; it contains most of the genetic material in the form of chromosomes. This is where the genes are situated. An egg, like a sperm, contains half the number of chromosomes as a normal cell, i.e. 23 each. The chromatin material inside the nucleus is composed of DNA, some proteins and RNA. In an enucleated ovum, DNA will be absent. The mature RBCs, mature spermatozoan and root hair are nucleated which contain DNA.

    Plant breeding is a science-based on principles of genetics and cytogenetic. It aims at improving the genetic makeup of the crop plants. Its objectives are to improve yield, quality, disease resistance, drought and frost-tolerance and important characteristics of the crops. The appraisal of the value of plants so that the breeder can decide which individuals should be discarded and which allowed producing the next generation is a much more difficult task with some traits than with others.
