Heterozygous - White gene carrier
Homozygous - No white gene
White tigers are not albinos and do not constitute a separate subspecies of their own and can breed with orange ones, although all of the resulting offspring will be heterozygous for the recessive white gene, and their fur will be orange. The only exception would be if the orange parent was itself already a heterozygous tiger, which would give each cub a 50% chance of being either double-recessive white or heterozygous orange. If two heterozygous tigers, or heterozygotes, breed on average 25% of their offspring will be white, 50% will be heterozygous orange (white gene carriers) and 25% will be homozygous orange, with no white genes. In the 1970s a pair of heterozygous orange tigers named Sashi and Ravi produced 13 cubs in Alipore Zoo, of which 3 were white. If two white tigers breed, 100% of their cubs will be homozygous white tigers. A tiger which is homozygous for the white gene may also be heterozygous or homozygous for many different genes. The question of whether a tiger is heterozygous (a heterozygote) or homozygous (a homozygote) depends on the context of which gene is being discussed. Inbreeding promotes homozygosity and has been used as a strategy to produce white tigers.
(From Wikipedia)
A white tiger is a normal tiger, but with an unusual fur color. Any difference will be down to the individual, and not the color.
The color
The only difference between white and normal tigers is the color of the fur. Any difference will be down to individual reasons, not color.
The white tiger has blue eyes where as others have brownish-black. It also has white fur with black stripes while other tigers have orangish-redish color fur with black stripes
Yes. The "white tiger" is a Bengal tiger with a white coat. The coat color is determined by a recessive gene that is specific to the Bengal subspecies.
They aren't different the White Bengal Tiger is just white and the Bengal Tiger is orange.
Currently, only in captivity. White Bengal tigers are not a seperate species from the normal Bengal tiger, but an extremely rare color morph. White cubs can appear at any time in a normal litter, but there are none known in the wild at this time.
the color
The Siberian tiger does not have white fur. Only a few color morphs of the Bengal tiger are white.
they are usually white and look kind of like a normal tiger
The rare white tiger is the same size as a normal tiger.
The only difference between a white tiger and an orange tiger is the gene that controls fur color. ANy differences in speed will be down to the individuals, and not their color.
