Melanic

There is no actual evidence that the melanic trait existed at any frequency above the background mutation rate before that. ❋ Unknown (2007)

… We tried to see whether the dark individuals were larger or stronger, but with negative ressults, though these individuals were more viable in breeding, an experience also reported by Harrison 1920 for British melanic moths. ❋ Unknown (2005)

… The idea arose, therefore, that the melanic forms wer in some way chaned in regard to their metabolism, and that this enabled them to feed on the poisoned food of the industrial districts. ❋ Unknown (2005)

Why were all such Sunday School rooms bile green, with those heinous Masonite tables and mustard-colored bulletin boards and the selfsame melanic upright piano with a plastic Jesus on top? ❋ Unknown (2002)

For example, every sportsman must have noticed that the somewhat rare melanic variety of the common rabbit will crouch as steadily as the normal brownish-gray type, notwithstanding that, owing to its abnormal colour, a "nigger-rabbit" thus renders itself the most conspicuous object in the landscape. ❋ George John Romanes (1871)

It is not impossible that some definite varieties, such as the melanic form of the jaguar and the bridled variety of the guillemot are due to this cause; but from their very nature such varieties are unstable, and are continually reproduced in varying proportions from the parent forms. ❋ Alfred Russel Wallace (1868)

Gross et al. [62] demonstrated empirically that the increase in melanic elytra in northern Europe and high altitude represent a selective thermal advantage at low temperatures in relation to the brightly coloured central European form. ❋ Marcus K. Drotz Et Al. (2010)

Unlike other lepidopteran melanic larvae mutations, this one is autosomal recessive and does not appear to involve a deficiency in JH titers. ❋ Unknown (2010)

Research on several species of melanic lepidopteran larvae have found that low levels of circulating juvenile hormone (JH) titers are associated with a melanic phenotype, suggesting that genetic changes in the JH biosynthetic pathway give rise to increased deposition of melanin granules in the cuticle in this group. ❋ Unknown (2010)

Some species of cat regularly produce melanic forms-the so-called black panther (actually a melanic jaguar) being the most familiar. ❋ Unknown (2010)

Hawkins K, Bermingham E, Ricklefs RE, Mundy NI (2001) The molecular basis of an avian plumage polymorphism in the wild: a melanocortin-1-receptor point mutation is perfectly associated with the melanic plumage morph of the bananaquit, Coereba flaveola. ❋ Pontus Skoglund Et Al. (2010)

This rise in frequency, if spread evenly over ~34 generations, would require an average increase by a factor of ~1. 36 per generation and is thus comparable to the most extreme selective events observed in natural populations, such as the spread of melanic moths in ❋ Unknown (2010)

The rise in frequency of the melanic (black) form of the peppered moth since the Industrial Revolution is a widely cited example of natural selection. ❋ Unknown (2009)

While variation in the Mc1r coding region does not correlate with melanism in any population, in a New Hampshire population, we find that a 125-kb deletion, which includes the upstream regulatory region and exons 1 and 2 of Agouti, results in a loss of Agouti expression and is perfectly associated with melanic color. ❋ Unknown (2009)

As for Norsk, its speakers trend more melanic than, say, speakers of Svensk. ❋ Unknown (2008)
