IV. Why this course ?
Silk production is affected by both the environment and the genetic background of
silkworm. The development of silkworm during its larval stage is crucial in obtaining
quality cocoon yield. Understanding the genetic mechanism involved in various
physiological and biochemical traits, which inturn influences the cocoon yield is
essential in planning silkworm breeding strategies.
V. Aim of the course
The course in designed to make the students realize that silkworm development is
influenced by the various physiological processes which are in turn governed by specific
genes. Finally the student learns the relationship between these processes, the
biochemical pathways and the genes that influence these processes and pathways.

VI. Theory
BLOCK 1: Developmental Genetics
Unit 1:
Embryonic development
Embryonic development of non-hibernating and hibernating eggs;
parthenogenesis; development of embryos under special genetic
conditions, i.e., controlled by E- group allele
,
NC gene, NI-gene.
Unit 2:
Post-embryonic development
Induction and translocation of quantitative and qualitative traits in
silkworm. Quantitative traits affected by maturity genes, influence of
environmental conditions on the expression of quantitative characters.
Inheritance of moultinism, voltinsim and juvenility.
