1. Tom and Tina decided they wanted to start a family. Tom knew his grandfather had sickle-cell disease. Sickle-cell disease is a recessive disorder that causes blood cells to stiffen and take on a crescent shape. These blood cells have a difficult time moving through the blood vessels and can cause health problems. Tina didn’t know of any family members that had it. Still, before they got pregnant they both went to the doctor for genetic tests. The doctor found that even though Tom and Tina were healthy, they both carried the gene for sickle-cell disease. Make a Punnett Square to determine the probability of Tom and Tina’s child having sickle-cell disease.

Use the space below to tell the probability of Tom and Tina having a child with sickle-cell and explain how you determine that.

Answers

it depends if their parents carry the gene, but from what we know, it is a 50% chance that the baby will have the disease.
