According to the pedigree, is cystic fibrosis inherited as a dominant or as a recessive allele traitKey male with Huntingtons affection unaffected male female with Huntingtons Disease unaffected female Generation I II III IV V Pedigree showing Inheritance of Huntingtons Disease Key male with Huntingtons Disease unaffected male female with Huntingtons Disease unaffected female Generation I II III IV V Pedigree showing Inheritance of Huntingtons Disease ? Explain how you make your conclusion utilize evidence from the pedigree and the principles of factortics.cystic Fibrosis is considered to be a recessive trait. If a person has only one of the Cystic Fibrosis gene and one of the non-Cystic Fibrosis genes, the person could be a carrier of the Cystic fibrosis gene without having the Cystic Fibrosis unhealthiness. Referring back to the mentioning of Mendel, which states that the traits may not show up in a person but still groundwork be passed down to the another(prenominal) generation. Mendel also mentioned that the inheritance of each of the trait can be inflexible by the genes that can pass down unchanged.Therefore if the Cystic Fibrosis gene is not present, it can become present dependent on the ratio of the amount of genes when it passes down. 2. What would a Punnett square that shows how the son in generation IV (marked with an A) inherited cystic fibrosis realise like ? Aa A AA A a a Aa aa Key male with Huntingtons complaint unaffected male female with Huntingtons disease unaffected female Generation I II III IV V Pedigree showing inheritance of Huntingtons disease Key male with Huntingtons disease unaffected male emale with Huntingtons disease unaffected female Generation I II III IV V Pedigree showing inheritance of Huntingtons disease B B Questions 1. According to the pedigree, is Huntingtons disease inherited as a dominant or as a recessive traitKey male with Huntingtons Disease unaffected male female with Huntingtons Disease unaffected female Generation I II III IV V Pedigree showing Inheritance of Huntingtons Disease Key male with Huntingtons Disease unaffected male female with Huntingtons Disease unaffected female Generation I II III IV VPedigree showing Inheritance of Huntingtons Disease ? Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. According to the pedigree, it is my belief that the Huntingtons disease is a recessive trait. My reason for the belief is that one of the family members at the beginning of the pedigree was affected by the disease. Also in the third generation, there was no family members affected as well. If the trait was dominant, more family members in the earlier stages of the pedigree would have been affected. 2.What would a Punnett square that shows how the first daughter in generation II (marked with a B) did not inherit Huntingtons disease look like? Bb Bbb 3. What is the role of chromosomes in the inheritance of genetic traits, such a cystic fibrosis and Huntingtons disease? The genetic traits are carried by the chromosomes. Within the normal cell, the chromosomes each have both parts which is the chromatids. There is also a reproductive cell which is made through the process called meiosis. The meiosis has only one chromatid for each of the chromosomes.Genetics WorksheetGenetic Worksheet Misanna Gordon SCI 230 December 02, 2012 Mitzie Sowell Associate Program Material Genetics Worksheet Review the images below and answer the follow-up questions.

Referring back to the mentioning of Mendel, which states that the traits may not show up in a person but still can be passed down to the other generation. Mendel also mentioned that the inheritance of each of the trait can be determined by the genes that can pass down unchanged.Therefore if the Cystic Fibrosis gene is not present, it can become present dependent on the ratio of the amount of genes when it passes down. 2.
