Hi Michael,

Given your first sentence, the rest all fits properly. However the word
"tabby" properly refers to the effects of two other genes (not the sex
linked orange or black); these are the one that controls whether the agouti
pattern of light tips to the hairs is expressed at all (thus the difference
between all black appearance or patterned in black and greyish, noting also
that this gene is non-functional in orange parts of cats), and the actual
pattern of mostly regular bars (mackerel pattern) or irregular pattern

One last obvious thing to say is that whilst many genes have a dominant /
recessive relationship between the alleles, the sex linked orange or black
gene in cats does not.

 My apologies Philip, by "tabby" I meant "ginger", no black blotches.

En paper perhaps not, but of say a dozen ginger cats seen by me over the
years, including pets pre enlightenment , none were xx phenotypes, they all
had testes.
