What is Pedigree Worksheet 1?

Pedigree worksheets are commonly used to analyze and understand the transmission of genetic traits from one generation to the next. Pedigree Worksheet 1 is a worksheet designed to explore the inheritance of Sickle Cell Anemia, a genetic disorder that affects the production of red blood cells and can cause severe health complications.

What is Sickle Cell Anemia?

Sickle Cell Anemia is an inherited, chronic condition that causes red blood cells to become sickle-shaped. This affects the way the cells move through the bloodstream and can cause a range of serious health problems, such as anemia, infections, and organ damage. It is caused by a mutation in the gene that codes for the production of hemoglobin, a protein in red blood cells that helps transport oxygen throughout the body.

How is Sickle Cell Anemia Inherited?

Sickle Cell Anemia is an autosomal recessive disorder, meaning that it is only expressed when two copies of the defective gene are present. When both parents carry the gene, their children have a one in four chance of inheriting the condition. If only one parent carries the gene, their children will not have the condition, but will be a carrier of the gene.

What is Pedigree Worksheet 1?

Pedigree Worksheet 1 is a visual tool used to help understand the inheritance of Sickle Cell Anemia. It consists of a family tree, with symbols that represent family members, their genotypes, and the inheritance of the condition. By analyzing the genotypes of the family members, it is possible to trace the transmission of the disorder.

Getting the Answers to Pedigree Worksheet 1

To get the answers to Pedigree Worksheet 1, you will need to analyze the information on the family tree and determine the genotypes of each family member. Once you understand the genotypes, you can then determine who has the condition and who is a carrier. By understanding the pattern of inheritance, it is possible to trace the transmission of the disorder through the generations.
