Any one good at Punnett Squares?(for hamsters)

So, does that mean it's recessive?

See, if it's recessive, each parent could have Dd as the genotype and 25% of the offspring (probabilitcally

– but it could always turn out more or less) could be spotted.

Sorry...very, very ignorant when it comes to genetics of any sort.

Thanks, you got more then I did,lol.

If it was recessive,then it could be carried,but it cant so its dominant. (I think

)

Well I guess I'll have my answers if the breeding took and I have a litter in a few weeks,lol

But if it can't be carried, how can two parents without spots have offspring with spots?

I'm sure I know hardly more about this than you do – if not less.

 

[NewHopePoultry]

Only one parent needs to have the Dominant Spot gene for the babies to have spots.
If you breed two of them together, then the litter is smaller becouse the gene is lethal if the animal has it twice.
You cant get spotted offspring if neither one of the parents is spotted.

I just ran across a website that said Short Hair is L-

Maybe this will help...a little....

Maybe this – I didn't actually look at the pages:

If you want to know how to do a Punnett Square, it's quite simple:

Take the genotype of the male and the genotype of the female – let's say the male's is BB and the female's is Bb (let that stand for whatever you want). Put one genotype on the top (usually I use the male) and the other on the left side of a square. Take the letter from the top and the letter from the side and put them together (capitals always go first). If I could get squares on here, it might make more sense.

B B
B BB BB

b Bb Bb

Can you get any live spotted from two spotted parents?

I have both of those links saved already

The Dominant Spot gene is a dominant and lethal gene. Being dominant means that a hamster only needs one of these genes, and he will have the dominant spot pattern. It also means that the gene cannot be carried.

The lethal part of the gene means that there are no hamsters with two Dominant Spot genes. All have only one dominant spot. Those hamsters who did have two Dominant Spot genes (got one from each parent) die in the womb and are reabsorbed by the mother. It does her no harm. It does mean that litters born to two Dominant Spots have 25% fewer babies on average than those born to a Dominant Spot and a non-Dominant Spot. The remaining babies are typically perfectly normal and healthy.

Haha – and I thought I was making a great discovery...but, no, you'd already said that your female's genotype for Dominant Spot is Dsds.... Never mind.

 

[wordgirl]

So then...

If male is dsds and female is Dsds, then... 50% of offspring will have genotype Dsds and be spotted; and 50% of offspring will have genotype dsds and not be spotted.

Maybe this is what you'll have:
