What is the importance of apomixis and polyembryony? At least 4-5 points.....
Apomixis is a type of asexual reproduction which does not involve fertilization. It does not lead to seed formation.
Importance - 1.Hybrid varieties of seeds can be produced which provide higher and better yield.
2.) Produce better clones and cuttings .
3.) Embryos so formed are generally free from infections .
4) Apomixis prevents the loss of specific characters in the hybrid. Also, it is a cost-effective method for producing seeds.
5) Apomixis is important for crop yield multifold.
Suppose that the crop's yield is 10 tones per hectare. So here, a two-fold increase would mean that the yield is doubled, a three fold increase will mean that yield is increased by three times. Similarly, a multifold increase will mean that the crops yield in increased many a times.
Polyembryony is the process in which the fertilization of single egg leads to the formation of two or more embryos.
Importance: It is important in the formation of identical twins. Formation of embryos by cells of the embryo sac other than the egg. Embryos develop from additional embryo sacs in an ovule.
