Paragraph 1
Scientists have unravelled a long-standing
about the feline world. Geneticists from Kyushu University in Japan have discovered why eight out of ten ginger cats are
. Dr Hiroyuki Sasaki discovered that a
in the X chromosome is responsible for a
unknown "orange gene". Dr Sasaki said: "Identifying the
has been a longtime
, so it's a
to have finally cracked it." The gene is responsible for pigmentation in the
of animals. Male mammals have an X and Y chromosome. If the male cat's X
has the gene, it will be a ginger. Because a female cat has two X chromosomes, the gene needs to be present in both for the cat to be orange. This is less
to happen.
