Basenji Health Issues & Questions
  • M

    ok i have a question. When you are doing a punnett square, lets say you have a dog that is DDKkYy and DDkkYy. Would you put one parent on top and one on the side and do the addition?

    …...kk.....Yy
    Kk..Kkkk…KkYy
    Yy..kkYy...YYyy

    How do you figure out what the puppy is? I dont understand how to take a parents code and put it into the punnett square. I know how to use the punnett square once its ready to be solved but i dont know how to determine where things go and how to evaluate the results (if there are more than 1 letter on each side)

    @Monika:

    example

    red x whait Dd kk ayay

    black x white
    Dd Kbrk ayay

    DD kk ayay = red x white
    Dd kk ayay = red x white
    dd kk ayay = blue fawn
    DD Kbrk ayay = brindle
    Dd Kbrk ayay = brindle
    dd Kbrk ayay = fawn brindle

    Dd Kbrk ayat = brindle
    dd Kbrk ayay = blue brindle
    dd Kbrk ayat = blue brindle
    dd Kbrk atat = blue trindle

    Im not sure what all this means. ayat are Yy. umm could you do it with Yy instead of ayay or atat? its just easier for me if you do. thanks

    Big Y is a red
    small y - tricolor,saddle,agouti and recesiv gen.Can not have four different meanings

    Misspodhradsky:

    tri factored black dog - Kk ayat
    tri factored red dog - kk ayat

    Use punnett square for K locus and another punnett square for A locus:

    ….......K........k
    k….....Kk.......kk
    k........Kk.......kk

    So, we have Kk (twice) and kk (twice)

    A locus:

    …............ay..........at
    ay….......ayay.....ayat
    at..........ayat......atat

    We got ayay, ayat (twice), atat

    Than put both, K and A locus, together (every K result with every A result):

    Kk ayay - black
    Kk ayat - tri factored black
    Kk atat - tri factored black

    kk ayay - red
    kk ayat - tri factored red
    kk atat - tricolor

    Or, with your letters:
    tri factored black dog - Kk Yy
    tri factored red dog - kk Yy

    ….......K........k
    k….....Kk.......kk
    k........Kk.......kk

    …............Y..........y
    Y….......YY.........Yy
    y..........Yy......yy

    And than again, put all together:

    Kk YY - black
    Kk Yy - tri factored black
    Kk yy - tri factored black

    kk YY - red
    kk Yy - tri factored red
    kk yy - tricolor

    Yes i know that. But when you put ay, at, etc. it confuses me. I need the coding to be is Y,y, K, and k. I think thats it. but i cant follow when people add in different letter cuz i dont understand it :(

    Which sucks cuz when you use letters i know it starts getting easier and easier lol

    OH! ok! so you dont do them all together. you do letter with letter and then add them! Oh ok!!! Thank you soo much! That helps alot!

    Kk YY - black

    Kk yy - tri factored black

    kk YY - red
    kk Yy - tri factored red
    kk yy - tricolor

    Where did you get the bold ones. I understand how to get the others but if you do it and add them together it makes no sense. …to me

    OR do you have to do

    1....2
    3....4

    1...2
    3...4

    do you have to do 1 with 1, 1 with 2, 1 with 3, 1 with 4....then 2 with 2, 2 with 3, 3 with 4....then 3 with 3, 3 with 4....then 4 with 4. and then take all the alike genes and group them. then take all the unalike genes and
    that is how you go the 2 extra genes?
    (I used 1,2,3,4 just to make it easier to understand than using letters K, Y, etc.)

    from K locus we got:
    Kk (and again Kk) - 1
    kk (and again kk) - 2

    from A locus we got:
    YY - a
    Yy (and again Yy) - b
    yy - c

    1 + a = 1a (Kk YY)
    1 + b = 1b (Kk Yy)
    1 + c = 1c (Kk yy)
    2 + a = 2a (kk YY)
    2 + b = 2b (kk Yy)
    2 + c = 2c (kk yy)

    2 + c = 2c (kk yy)

    Oh ook i think i get it now, thx for the help in clearifying it. so would "A" always be YY, "b" always be Yy and "C" always be yy? or is that just for this example?

    oh. so how do you know what to use then. :(

    It depends on the alleles of the dog. The litter that I co-bred and have been posting puppy pictures of the parents are KkYy and KkYY. If you do the two punnet square way instead of the 16 punnet square way you would get.

    At the K locus

    ….......K........k
    K........KK.......Kk
    k........Kk.......kk

    At the A locus

    .............Y.............y
    Y..........YY...........Yy
    Y..........YY...........Yy

    So we get

    from K locus we got:
    KK - 1
    Kk (we get this twice) - 2
    kk - 3

    from A locus we got:
    YY (we get this twice) - a
    Yy (we get this twice) - b

    1 + a = 1a (KK YY)
    1 + b = 1b (KK Yy)
    2 + a = 2a (Kk YY)
    2 + b = 2b (Kk Yy)
    3 + a = 3a (kk YY)
    3 + b = 3b (kk Yy)

    @jengosmonkey That is a very interesting link. My girl suffered none of the possible side effects. No lethargy, listlessness, weight gain and her shape remained immaculate till the day she died. But she no longer suffered from IBS.

    Yeah you told me about that before and I'm clueless, but I'll try it if I need to, lol. could be the noise of occasional thump, could be they can hear it even tho we can't. My chow would be drooling buckets before we got a mile away. I just had to keep towels down and take off and bag along the trip. But I took her for a 7 hr trip to atlanta and she threw up and threw up, then stopped. Never threw up again. :( on your back. I had been getting radiofrequency ablations in the US, and they really helped. But doctors here will only do them once or twice. I have had at least 6 on one side, 3 on the other. :( But it's miraculous pain relief when it is done right. Maybe your dog acupuncturists knows of a human one they'd recommend?

    I haven't studied coat colour inheritance in dogs, but from what I know of it in horses, you can tell quite a lot by looking at sire and dam and grandparents. Sometimes you can rule certain colours in or out, and determine probabilities of the colours you will get in a mating. Someone who knows more about dog colour genetics will be of more help. If an animal is homozygous for a trait, or heterozygous can sometimes be determined by knowing the colour of the parents…..

    Our red girl dog has the same problem. Freaks out when you touch her ears with a swab, but loves the inside of her ears rubbed when petting her. You know the two handed ear & cheek rub. That gave me an idea!. I found some real soft white - tight gardening gloves (unused), gave her an ear massage and cleaned her ears out. it worked well. I was extra careful not to push the dirt down her ears, but did kind of a wiping motion out and away from her inner ears. She loved it!

    Thank you so much for the encouraging words. We have been running him with our other dogs in our yard, we have about half acre or so, and he is fast..He loves it, just don't think he is used to out heat yet, it is already about 85+ degrees and very humid…I think he looks good, he is definitely babychunky, not fat, but what I envision a puppy looking like before he grows into his own body. We will keep up with what we have done so far and see what he turns out like...can't be bad, just beautiful.. Basenjimamma
