White tiger's coat
down to one change in a gene
Chinese scientists have acquired new insights into how
white tigers get their colouration.The researchers have traced the cause to a
single change in a gene known to drive pigmentation in a host of animals,
including humans. White tigers
are a rare variant of the customary orange Bengal sub-species. Today, they are
found exclusively in captive programmes where the limited numbers are interbred
to maintain the distinctive fur colour.Shu-Jin Luo of Peking University and
colleagues report in the
journal Current Biology how they investigated the genetics of a family of
tigers living in Chimelong Safari Park in Panyu, Guangzhou Province.

Could cryptids be the
result of a single gene change at some point in the past? Would explain their
scarcity and rarity.
