More than 80% of codes in both transcripts were similar; the remaining divergences were discussed by the research team until consensus about coding was reached.
This included a sound calibration of photometric sensors, whose cosine-response appeared at the end to be responsible for the remaining relative divergence observed between the daylighting performance figures.
Thousands of duplicated genes remaining after divergence of teleost species have subsequently undergone non-reciprocal loss, pseudogenization, or sub-functionalization, and may be associated with unequal microsynteny in flounder and zebrafish.
In the remaining genes, divergence in allelic expression was classified in three categories with no clear majority among the three: on average, 15.5% in the cis-regulatory category alone, 18.5% in the trans-regulatory category alone, and 17.5% in the cis- + trans-regulatory categories (fig. 4 B), in the two groups of hybrids.
The remaining interspecific divergences were dated to ca. 9 Ma (A. strepitans) and 7 Ma (A. cingulata – A.zelandica split).
The three stages remain; 1) divergence of Amerind ancestors from the Asian gene pool, 2) prolonged period of isolation, lasting at least 7 15 thousand years, during which time genetic variants specific to and present throughout the New World were generated, and 3) rapid expansion into the Americas ∼16 kya concomitant with a large population increase.
For the duplication and speciation nodes supported by PP ≥ 50%, 54 duplications occurred after the mygalomorph araneomorph divergence, 68 before the divergence of scorpions and spiders, and the remaining 41 between the two divergence events.
OLFR genes give a fitness advantage by duplication and divergence while remaining active, yet must also retain regulatory information.
By contrast, the remaining pairs exhibited significant divergence of expression, which supported the notion that the expression of paralogs can diverge significantly after duplication.
