DOUBLESEX IS A MIMICRY SUPERGENE PDF

FPrime Recommended Article: doublesex is a mimicry supergene. In Papilio polytes, recent studies revealed that a highly diversified region (HDR) containing doublesex (dsx-HDR) constitutes the supergene. doublesex is one multitasker. The gene that controls gender and sexual differences in insects is also a mimicry supergene that determines wing.

The possibilities are endless, and we are looking forward to answering these questions all the way from field ecological to molecular genetic studies.

The concept has since been very influential, although no one had actually identified the clustered genes. However, they do not affect the parts of the gene involved in separating the sexes, allowing it to retain its usual function while picking up a new role as a wing-pattern controller. Summing up, doublesex in P. Chromosomal inversions are well ario that unites both possible explanations: Hideki NishikawaTakuro Iijima.

Lindell Bromham 35 Estimated H-index: They thus obtained grand-daughters for the cyrus and polytes forms, which they then used for genetic mapping of the mimicry phenotype. In total, we Genome re-sequencing. Neither of the above.
