geographical race

a population separated by geographical barriers from other similar populations and possessing features (morphological, physiological or genetic) by which the population can be characterized; fertile offspring result from interbreeding with other populations of the same species.

Earlier, the description of geographical races was exclusively based on colour and size of honey bees.
The proboscis length of various geographical races of honey bees has shown considerable variations.
Earlier, the fore wing length and width have been reported to be variable (Ruttner, 1988; Jevtic et al., 2007; Adl et al., 2007) which can be attributed to altitude or geographical races. Dyer and Seeley (1987) reported the fore wing length in A.
As a country, five geographical races of honeybees (Apis mellifera monticola, Apis mellifera bandasii, Apis mellifera scutellata, Apis mellifera jemenitica, and Apis mellifera woyi-gambella) are reported to exist in different agroecological zones [4].

Its geographical races have different coloration patterns that range from orange and black, to red, yellow, and black, and to iridescent blue and pink (this pattern of coloration is shared with the co-mimic H.
Measurements taken from the museum specimens support the hypothesis that geographical races from the eastern side of the Andes tend to be larger than the geographical races from the western side of the Andes (Table 1).
Differences in wing size in geographical races of Heliconius erato distributed on the western and eastern side of the Andes are reported here.
Using these statistics, race theorists argue that there can be no justification for recognizing human geographical races. Populations are clustered so closely together that any partitioning into races would be merely subjective.
This diversity confounded the systematic efforts of 19th-century collectors, who applied dozens of names to divergent geographical races and to the hybrids between them, which displayed a spectrum of recombinant wing patterns (e.g., Weymer 1893; Riffarth 1901; Stichel and Riffarth 1905; see references in Neustetter 1929).
Why should butterflies participating in Mullerian mimicry rings exhibit numerous parapatric geographical races with radically different phenotypes, when theoretically predicted to show monomorphism across their distribution?
