Enlist steps of process of hybridisation in crop breeding. Give one advantage of hybridisation.

Give one advantage of artificial insemination.

In hybridisation, the haploids combine the advantages of

Mention one advantage of crop rotation.

Mention one advantage of mixed cropping.

In order to explain the characteristic geometrical shapes of polyatomic molecules, Pauling introduced the concept of hybridisation. The orbitals undergoing hybridisation should have nearly same energy. There are various types of hybridisations involving s, p and d - type of orbitals. The type of hybridisation gives the characteristic shape of the molecular or ion. Which molecule does not have the same type of hybridisation as P has in PF_(5) ?

Explain the process of artificial hybridisation to get improved crop, variety in (i) plants bearing bisexual flowers (ii) female parent producing unisexual flowers.

How is somatic hybridisation carreied out? Mention one example of a somatic hybrid.

In which of the following process, hybridisation of the central atom changes?
