These two, because there's a Y chromosome, these would be them having a son. Figure 2. Example punnet square for sex-linked recessive trait. Eye color in Drosophila was one of the first X-linked traits to be identified. Well, the daughters are going to be the XX scenarios.
Science High school biology Classical genetics Sex linkage. In flies, the wild-type eye color is red X W and it is dominant to white non sex linked punnett square in Gosford color X w Figure 1. Show Answer Both parents must be colorblind—or the father is colorblind and the mother is a carrier for colorblindness.
Now, consider a cross between a homozygous white-eyed female and a male with red eyes Figure 2. Now, what's useful about this Punnett square is you could answer all sorts of questions.
Discoveries in fruit fly genetics can be applied to human genetics. Another example of incomplete dominance can be found in rabbits: when a long-furred Angora breeds with a short-furred Rex, the offspring have medium-length fur. Example punnet square for sex-linked recessive trait.
When a female parent is homozygous for a recessive X-linked trait, she will pass the trait on to percent of her offspring. And so this is a situation where you have a daughter, daughter with hemophilia, hemophilia, right over here.
Well, non sex linked punnett square in Gosford would say, given that they have a son, so that would be those two scenarios, one out of those two scenarios, the son does not have hemophilia.
Next lesson. In Drosophila, the gene for eye color is located on the X chromosome. Example punnet square for sex-linked recessive trait. And so this is a situation where you have a daughter, daughter with hemophilia, hemophilia, right over here.
So, there you go.
