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.

Diversification of doublesex function underlies morph- sex- and species-specific development of beetle horns. Long-term balancing selection, which architectures, such as self-incompatibility in plants and segregation maintains mimicry polymorphism1,8,12, is expected to result in a loca- distortion in Drosophila melanogaster, have also been traced back to lized excess of nucleotide variation driven by the accumulation of neut- multiple linked genes16, However, we note that the proportion of fixed 12 dsx differences between cyrus and polytes haplotypes is over seven times greater in coding regions 72 out of 1, differences compared to 10 non-coding regions out ofdifferencesand these coding region changes include 25 amino acid substitutions located primarily 8 in the first exon Table 1.

We extracted genomic DNA from 30 laboratory-reared generated nine backcross mapping families, yielding a total of backcross individuals 15 polytes and 15 cyrus. These females mimic the colors, wing patterns and even shape note the small spuergene projections on the hindwings of the Pachliopta models.

The authors declare no competing financial interests. Skipper genome sheds light on unique phenotypic traits and phylogeny.

A single gene can perform different functions if it can manufacture different proteins. We focused end-sequencing and BLASTing against the protein nr database, we recovered on the region surrounding dsx and large structural variants. Received 27 November ; accepted 30 January A startling revelation which, coupled with a revision of what supergenes are, makes the study an important mimmicry in evolutionary genetics.

Genes accomplish this by a process called alternative splicing, where different portions of a single gene are removed and re-structured to form isoforms.

But such differences can also be lost during recombination, the usual shuffling of genetic variation at the time of sexual reproduction. The Genetical Theory of Natural Selection.

Kunte and Kronforst found that the mimetic version of doublesex is inverted relative to the non-mimetic one, so it sits in a different orientation in the genome.
