How can learning genetics benefit you?

Taking time to learn about genetics can help you understand your own health and make healthy choices. Genes that do not work correctly can cause problems. A group of rare diseases are caused when a single gene stops working normally.

What is the role of genetics?

Genetics is the study of how different qualities, called traits, are passed down from parents to child.

When we trace the paths of these qualities, we are following packages of information called genes.

How do genetics affect us?

Genes can carry instructions that can make it more likely for you to develop certain illnesses or conditions. For example, Jennifer and Karen both have genes associated with obesity. Their genes could tell their body to: increase the size of their fat cells or dictate how they use fat in their body.

What genes are inherited from mother only?

And, mitochondrial DNA (or mDNA) is inherited strictly from the mom. Because mDNA can only be inherited from the mother, meaning any traits contained within this DNA come exclusively from mom—in fact, the father’s mDNA essentially self-destructs when it meets and fuses with the mother’s cells.
