Final answer:

Identical twins and parent-child relationships result in 50% shared genes due to genetic inheritance.


Explanation:

Identical twins will have precisely 50% of their genes in common. This is because they are derived from the same fertilized egg, making them genetically identical.

When considering parent and child, the child inherits half of their genes from each parent, resulting in 50% shared genes with each parent.

Understanding Mendel's Law of Segregation helps explain how genetic traits are passed down from parents to offspring with equal likelihood.
