Genetic biology

This assignment will be worth 20 points, instead of the normal 10. I think genetics is very important and more interesting. Chances are that either you or someone else you know may have to see a genetics counselor at sometime during their life.  GeneticsActivitySp2020.docx Genetics Activity You are a genetic counselor. You have been given 2 case studies of a couple who have been trying to have children. For each case, you will do a Punnett Square and determine what the chances their offspring have of inheriting the condition. Using these chances, you can make a suggestion as to whether or not they are risking having a child with a debilitating condition. Some of these conditions are life-threatening. Other conditions allow for a good quality of life with a few lifestyle modifications. Genetic Condition #1 Hereditary methemoglobinemia (meth-H)  Located on chromosome #22  Autosomal recessive  Those afflicted appear blue or purple in color due to inability to carry oxygen in the blood  Can cause seizures, coma, and death if levels of oxygen are too low  Can be easily treated with oxygen and methylene blue  The father is healthy and not a carrier of the trait (homozygous dominant). The mother has a family history and her father exhibited the trait, but she appears healthy (heterozygous).   What is the mother’s genotype (indicate with letters)?   What is the father’s genotype (indicate with letters)?   Draw a Punnett Square in the space below             How many of the offspring would be afflicted with the inherited condition?     Given the condition background provided, what do you suggest the couple do? Genetic Condition #2 Achondroplasia dwarfism  Located on chromosome #4  Autosomal dominant  Adults have shortened limbs and may experience joint paint, increased ear infections and sleep apnea  The average male is 52 inches in height and the average female is 48 inches in height as an adult  Life span for most individuals is decreased by 10 years  If both parents pass on a mutant gene, babies may only live for a couple of months  Both parents are heterozygous for the trait.   What is the mother’s genotype (indicate with letters)?   What is the father’s genotype (indicate with letters)?   Draw a Punnett Square in the space below               How many of the offspring would be afflicted with the inherited condition?       Given the condition background provided, what do you suggest the couple do?  PreviousNext
