is family, for
The study of genetics is based on the fundamental cause and effect relationship between genes
and traits. We inherit our genes from our parents, which then causes us to have particular
traits. Use the models provided that illustrate different aspects of inheritable traits, and
construct an explanation for what causes siblings with the same biological parents are each
unique.
You must use evidence from each model to support your explanation.
Answer
Siblings with the same biological parents are each unique because they inherit different combinations of genes from their parents. This is illustrated by the Punnett Square, which shows that each parent contributes different alleles to their offspring, and the Pedigree Chart, which shows that each generation has a unique combination of genes. This means that siblings will have different combinations of genes, which will lead to different traits and make them unique.
