3.4 2 What Is The Probability

Question: Sickle Cell Anemia

Answer: An inherited recessive disorder.

Question: Chromosome

Answer: Each parents has two copies so there is a 50% chance of their chromosome being passed to a child.

Question: Genetics

Answer: The science of genes, heredity, and the variation of organisms.

Question: Punnett

Answer: A simple graphical way of discovering all of the potential combinations of genotypes, given the genotypes of the parents.

Question: LAB Part 1: Predicted Results

Answer: We first set up a Punnett square and complete one. We then determine the phenotypes associated with each genotype. After, we determine the chance for a child to be born with sickle cell anemia based on the Punnet Square. We then determine the genotypes for the parents in Activity 3.3.1.

Question: Phenotypes and Genotypes

Answer: SS: Normal

Ss: Carrier

ss: Sickle Cell

Question: Calculation for Punnett Square

Answer: # of Boxes Containing the Phenotype you want divided by 4 and multiplied by 100.

Question: Genotypes for the Parents in 3.3.1

Answer: Father: Sickle Cell

Mother: Carrier

Question: LAB Part 2: Experimental Results

Answer: We then use the data table from 3.3.1 to determine the different percentages for the children that have diseases or are carriers.

Question: Percent of Children with Sickle Cell Anemia

Answer: 16%
