Genetics is the difference between the pink silkworm cocoon or the white cocoon. Silkworms in the wild spun yellow silk to blend into the dead foliage. Today silkworm farmers are beginning to selectively breed for different colors.
a yellow cocoon! its not surprising, it could be a silk worm cocoon are you surprised, silkworm cocoon's can be yellow AND white, also there's two kinds, I talked about the first one, it could be the other kind too!
Your Answer is here... Qualitative and quantitative differences in proteins expressed in the middle silkglands of male and female silkworm larvae that differ in silk colour were investigated by high resolution two-dimensional polyacrylamide gel electrophoresis (2-D PAGE), followed by computer-assisted image analysis. About 1000 protein spots were resolved in both the sexes and most of the proteins ranged from 15 to 70 kDa and pH 4-8. Some proteins displayed higher expression in yellow cocoon, while two proteins were only expressed in female silkworm silkgland tissue through comparison and analysis using the 2-D software. These proteins especially existed in female silkworm middle silkgland tissue of yellow cocoon. Furthermore, these proteins might be involved in the expression of cocoon colour phenotype. Regards, M.
