Have you ever been told by elders, 'You look just like your dad!' or 'Your eyes are exactly like your mom's'? This isn't a coincidence. In biology, this is known asheredity.

Learning Objectives

• Understand that offspring typically inherit traits similar to those of their parents.
• Identify hereditary traits versus non-hereditary traits.
• Learn to respect individual differences.

Core Content: Why Do Children Resemble Their Parents?

Offspring of animals and plants often retain certain traits from their parents. These traits act like life’s blueprint, passed down from parents to children.

• Human Examples: Skin tone, eye color, earlobe shape (attached or detached), ability to roll the tongue.
• Plant Examples: Petal color, number, or leaf edge shape.

However, these similarities do not mean they are identical. While you inherit traits from your parents, each individual still has their owndifferences, making everyone unique. This 'variation within similarity' forms the foundation of biological diversity.
