Silkworm breeding is aimed at the overall improvement of silkworm from a commercial point of view. The major objectives are improving fecundity (the egg-laying capacity of a breed), the health of larvae, the quantity of cocoon and silk production, and disease resistance.
A draft genome sequence for silkworms was released in 2004, and at least three re-sequences have followed, discovering genetic evidence that the domestic silkworm has lost between 33–49% of its nucleotide diversity compared to the wild silkworm.
Pasteur’s germ theory of disease initially seemed to have resolved the long-standing antagonism between the proponents of intrinsic and extrinsic disease mechanisms. However, by the turn of the 20th century, it had become clear that each microbe killed only a small minority of infected individuals. Infectious diseases killed half of all children before the age of 15 y, but this enormous.

It is not surprising that animals which breed so fast and occupy so little room as silkworms should have afforded the material for the experimental investigation of heredity.
This hypothesis has become a classic theory of the inheritance of quantitative character [2]and has been popular so far over the world. In this study, an alternative analysis was done for this experiment and it pointed out the misjudgments of genetics community in the world and drawbacks of this hypothesis.

The juvenile–adult transition is a key developmental process in organisms. A long-held paradigm in insect endocrinology is that juvenile hormones (jhs) prevent metamorphosis until larvae attain an appropriate size for the juvenile–adult transition. However, little is known about the roles for jhs during embryonic and very early larval stages.
Bombyx mori, the domestic silk moth, is an insect from the moth family bombycidae. It is the closest relative of bombyx mandarina, the wild silk moth.

A team of researchers affiliated with several institutions in china has conducted a genetic study of the silkworm in hopes of better understanding its long historical ties to humans.

In describing one of his experiment with silkworms, pasteur asserted that the microorganism present in such large numbers in the intestinal tracts of the silkworms were “more an effect than a cause of disease”. At the health conference in 1976, jonas salk noted that there are basically two ways to heal sick people.
Implicit in the classic view of inheritance is the assumption that a gene remains in a fixed location on its chromosome, with the noted exception of recombination during meiosis.
In the case of silkworms, aside from genetic divergence, whether epigenetic divergence played a role in domestication is an unanswered question.
In the silkworm, bombyx mori, a classic model organism for genetics and physiology, ommochromes accumulate in the pigment granules of egg serosa and compound eyes, thereby causing dark brown and black coloration, respectively (tazima 1978).
