madam [21]
Punnet square
Let's call black 'B' and white 'b'
Being intermediate, gray cats will have the alleles 'Bb'
Being recessive, white cats will have the alleles 'bb'
          <u>       Gray  </u>
          |<u>  </u>|<u>  B   |  b |</u>
White |b|<u>  Bb | bb|</u>
          |b|<u>  Bb | bb|
</u>
^Apologies for the awful drawing XD

Bb = Gray
bb = White
So the cats can have gray or white fur (A)

Temka [501]
