The hybrids express vigour in a particular character, by virtue of which they are superior to their parents. This phenomenon is called hybrid vigour or heteros..

Crop improvement by deliberate attempt to cross two parents of desirable characters to incorporate such characters in next generations is called breeding. The entire process of pollination, fertilization and regeneration is kept under control and selected parentsh..

Breeding - Crop improvement by deliberate attempt to cross two parents of desirable characters to incorporate such characters in next generations is called breeding. The entire process of pollination, fertilization and regeneration is kept under control and selected ..

Chromosomal Basis of Inheritance - Heredity depends upon the protoplasmic continuity between the parent and the offspring. It is the gametes that establish the continuity between parent and offspring and hence, the mechanism of inheritance operates across this exceedingly slende..

In the diploid number, chromosomes are always found in pairs. In each pair there are two identical chromosomes, called homologous chromosomes. These chromosomes are identical in size, appearance and position of the centromere. Apart from this, the two homologous chromosomes are genetically identica..

Heredity and Variation - All living organisms reproduce. Reproduction results in the formation of offspring of the same kind. A pea plant produces only pea plants each time it reproduces. A rat produces only rats. Humans produce only humans. However, the resulting offspring need not and most often ..

Hybridization is mainly utilized to evolve new hybrids having beneficial heterosis improve / incorporate a specific desirable character so that such progenies are used in further breeding process and desirable improvement can be brought in the concerned crop. A commercial hybrid is a hybr..

It is a type of intragenic (or interallellic) interaction where both the alleles of a given trait express as a blend (mixture) as against a normal Mendelian pattern where one allele is dominant over the other. As a resulting of this blending, an intermediate character is expressed. This s..

Incomplete Dominance - It is a type of intragenic (or interallellic) interaction where both the alleles of a given trait express as a blend (mixture) as against a normal Mendelian pattern where one allele is dominant over the other. As a resulting of this blending, an intermediate character..
