Learn@lllinois Get Help Status Page Ciara Johnson What is the likelihood that this individual inherited at least one non-functional allele predisposing him to cancer? Assume that every individual in thi spedigree that died of cancer was heterozygous with respedt to a cancer-supressor gene Individual died from other cause Individual died from colon cancer Living individual Note: To make calculating the probability more manageable, assume that every person who died of cancer in this pedigree was genetically predisposed to cancer. Also, cancer is a complex condition, resulting from malfunctioning of many proteins encoded for by many genes. For this problem, however, you may treat this condition as though this is a single-gene trait. Also, even though you technically dont know whether a person who died of another cause was not predisposed to cancer or not, for this problem, please assume that these individuals are NOT predisposed to cancr KEEP IN MIND THAT AN INDIVIDUAL CANNOT LIVE IF THEY ARE HOMOZYGOUS RECESSIVE This question is a challenge! It requires careful use of both the AND and the OR rules of calculating probabilities. This problem is far harder than anything you will see on your quiz or hour exam.Explanation / Answer
From the above Pedigree, we can conclude that the offspring in the T3 generation is having a parent with affected allele of colon cancer.
Colon cancer is cause due to several abnormalities or several gene mutations which allows the transition to their family members. They affect men and women equally, The offsprings of parents who carry this gene have 50% or 0.5% chances of getting this colorectal cancer.
