Quick Reference

The commercial silkmoth, which was domesticated in China from its wild progenitor B. mandarina about 5,000 years ago. Bombyx is estimated to contain about 18,510 genes in its genome of 429 mbp of DNA. There are about 400 visible phenotypes, and ∼200 of these have been assigned to linkage groups. The diploid chromosome number is 28, and the chromosomes are holocentric (q.v.). The female is a female-heterogametic species (ZZ in male, ZW in female). Sex is determined by a dominant feminizing gene on the W chromosome.
