13... take the pup and cross it with a smooth haired purebred dog and see if any pups come out smooth haired... with a dominate trait, if there is any part of the dominate trait inside a gene, the dominate trait will come through, so if there is any chance of the pup having the recessive smooth hair trait in his genes, there is a 1/4 chance that one of its offspring will be smoothair, if they all come out wirehaired, it is safe to assume that the dog is purebreed with the wirehair genes... Uh, ducks Im gonna have to look at.

did you know that one of the dominate traits in the human race was to have 6 fingers... it is a dominate trait, but it is so rare to find people with 6 fingers and toes that nobody believes it. |

Actually yes, itwas mentioned in one of the problems! It's called polydactyly.  |

Also there's a very small town (I forgot where) where almost all the people have the polydactyly trait! |

Observation 1. Both parents had the crested Dominate and non crested recessive trait... |

From Authorid: 42519
thus that is where the non crested ducklings came from...

Possibility: the 1/4 of the ducks that that did not hatch also did not have the crests also, so possibility that one parent had no crest, we dont know, the problem didn't tell us they both had crests, but we know they are crested ducks, so possibility that the non crested is also a weaker trait.... Im gonna go eat dinner, i will be back at cha with anything else I come up with. |

I cant remember the definition of Genotypes, so if you could help me out here./.... |

Genotypes are things like "Gg" "CC" The things used in Punnett squares. |

So your lookin at a butt load of ducks... some of them dont have crests, some do... so your lookin at probably the parents being a Cc and Cc *C for Crested Dominate* or you have the possibility of having a CC and cc, because like I stated, the duck is supposedly crested wether or not it has a crest... so your lookin at the possibility of the ducks bei....wait.. that doesn't work... Ok take out my possibility alltogether.... the possibity of one parent duck being a cc is not gonna work cuz all kids would have crests........ ok... possibility one removed... ok.... anyway..... |

Parents have to be a Cc and Cc cuz if it was a CC and cc, all ducklings would be crested... parents cant be Cc and cc because that would make more uncrested ducks than crested, so they have both the dominate and recessive traits in them..... ok.

So the kids have either the CC, Cc or cc... thus making the 1/3 of them not having the crest, 1/3 of them making only crested offspring and the rest having the possibility of crests or no crest... is that all you need?? |
