Dragons are usually shown in modern times with a body like a huge lizard, or a snake with two pairs of lizard-type legs, and able to emit fire from their mouths. The European dragon has bat-like wings growing from its back.A dragon-like creature with wings but only a single pair of legs is known as a wyvern.lthough the indigenous name for a dragon in Japanese is tatsu (ãã¤) , a few of the Japanese words for dragon stem from the Chinese word for dragon, namely, ryÅ« (ããã) or ryÅ (ããã) (traditional :é¾; simplified :ç«).
Each peppered moth in the samples was identified by phenotype as melanic (solid black), typical (patterned wings), or intermediate (insularia). The range of phenotypic differences results from multiple alleles at a single locus, with the allele producing full melanism as dominant (Lees and Creed 1977; West 1977).
In peppered moths, the allele for dark-bodied moths is dominant, while the allele for light-bodied moths is recessive, meaning that the typica moths have a phenotype (visible or detectable characteristic) that is only seen in a homozygous genotype (an organism that has two copies of the same allele), and never in a heterozygous one.
