45. This case could be repeat in the F2 generation if the offspring with blood type A crosses with an individual with blood type B or if the offspring with blood type B crosses with an individual with blood type A.
46. The offspring that needed the blood transfusion was the one who had blood type O, because people with this type of blood can only received blood from individuals with type blood O
47. Conclusion Why is it important of knowing about genetics?<br />Genetics is a branch of science that is uncharged of the studying the units of heredity in living organisms. Knowing about them has been useful for human kind since its origins in many aspects of life such as biology, medicine, agriculture, economy and evolution of human knowledge. Genetics has allowed scientist to improved crops of plants and animals through selective breeding in an effort to battle hunger and harden economy, also they have been able to understand and create solutions to multiple disease, that have to do with the inheritance of genes. Finally through genetics we have been able to clarify our minds, to find the possible source of our origin, and every day that passes in which science advance and with help of genetics we are closer to that answer.<br />
![Name: Tatiana Barragán Briceño, David Saavedra<br />Grade: 10° CB<br />Date: 21 de septiembre del 2010<br />Biology<br />WORKSHOP<br />,[object Object],In lab a group of scientist wants to know the F1 outcome in the cross of a red-eyed rat which is the recessive phenotype and a black-eyed rat, if both of them are homozygous to their gene. How they could know it?<br />,[object Object],During winter most of the birds immigrate to Canada, so it is easy to find different kinds of birds. One of the species found is long-winged with big peak, which is the dominant phenotype and another which is shorted-winged and with small peak. Which would be the cross in the F1 generation between a heterozygous long-winged big peak and homozygous shorted winged small peak?<br />,[object Object],Pablo has diabetes but none of his parents has. He would married with Anne which is a homozygous none diabetes woman. Which is the possibility that their kids have the disease? If Pablo has a sister, would she by diabetic? <br />The recessive allele determines if the person has or not the disease.<br />,[object Object],In a family, each of the four kids has a different blood type. Which are the genotype and the phenotype of the parents’ blood type so that this could be possible? This case could be repeated in the F2 generation? One of the offspring had a terrible accident in which blood transfusion was need, but he couldn´t receive blood of any of his relatives. Why was this?<br />Solutions:<br />,[object Object], Black-eyed: R<br />RRrRrRrrRrRr<br /> Phenotype<br /> 4/4: Black eyed rats = 100%<br />Genotype<br /> 4/4: Rr<br />,[object Object]](https://image.slidesharecdn.com/tatianaanddavidworkshop-110502180946-phpapp02/85/Tatiana-and-David-workshop-1-320.jpg)
