- Make up your own genetic problem involving your family. Make sure to draw a punnet square!Normal wife Affected husband As a genetic counsellor you are presented with a married couple where one of them has a family history of this disease. The husband is affected by this disease and the wife is normal. The couple, who are thinking of starting a family, would like to know what their chances are of having a child born with this condition. They would also like to know what the probabilities are of having an affected boy or affected girl. Use the symbols above to complete the diagram right and determine the probabilities stated below (expressed as a proportion or percentage). Parents 4.

A large letter is used for the dominant trait and a small letter for the recessive trait. When we want to describe the genotype of an organism, we use both letters to represent the alleles inherited from the parents. For example, free earlobes is a dominant allele and attached earlobes is recessive. You would use a capital "F" to indicate the dominant allele and a small “f" to indicate the recessive allele in describing an individual. 1. Write the three genotypes for earlobe attachment as it applies to the following individuals. a. Heterozygous b. Homozygous Dominant c. Homozygous Recessive 2. When it comes to symbolizing incomplete dominance with letters, it is best to use the letter "C" for one allele and "C'" for the other allele. List the three possible genotypes for hair type. a. Curly b. Wavy c. Straight. Why not use a small…
- The Meeting Sarah stared blankly at the blue paisley wallpaper. Her husband Mike sat by her side, bending and unbending a small paper clip. “Sarah and Michael, it’s good to meet you,” welcomed the genetic counselor, as she entered the room. “I apologize for being late, but I was just meeting with another couple. Let’s see, you’d like to have a child, but you’re concerned because of your family history of cystic fibrosis.” “Yes,” Sarah replied softly. “Mike and I met at a CF support group meeting a few years ago. He had a younger brother who died of cystic fibrosis, and I had a younger sister. We saw the painful lives they had—difficulty breathing, the constant respiratory infections. Although the treatments for CF are better now, we just don’t know if we can…” she trailed off. “I can certainly understand your concern,” the genetic counselor responded sympathetically. “That’s where I hope to help, by providing as much information and advice as I can. I’m glad that you came to see me…How do I solve for phenotypes?
