Understanding Eye Color Prediction
Predicting a child's eye color is no easy task, and it's important to note that the Mendelian model used for such predictions is inaccurate, despite still being popular.

Genes Genetics and Inheritance
Not all genes confer a dominant trait and having certain mutated genetic variants does not guarantee the development of an inherited disorder.

Hair Color Genetics
Hair color is a complex interplay of genetic factors, with more than one gene involved in determining exactly what shade will emerge: black, brown, blonde or red.

Mitochondrial DNA
DNA is a person's unique genetic map. It contains all of the information needed to make one, unique human being, unless it is mitochondrial DNA.

Repairing Chromosomal Breaks
A nick in the DNA strand is known as a chromosomal break. Cells have repair mechanisms for both single strand and double strand breaks.

How Cells Fight DNA Damage
Genetic disorders afflict millions and are caused either by inherited or acquired DNA mutations. This article outlines some ways human cells have for fighting DNA damage.

All People are Mutants
Since the beginnings of modern genetics scientists have been trying to figure out how often mutations occur; now they think they have the answer.

Micro-RNAs, Diseases and Therapy
Besides mediating between the DNA and proteins, RNA has a function in regulating the levels of proteins in the cell. This regulation is critical for the cell's behavior.

APOE Changes Alzheimer's Risk
A fairly common genetic variation makes many people at greater risk for heart disease and for dementia, but not for the same reason.

What is Epigenetics?
Epigenetics is the latest buzzword in biotech. Here's a quick primer on how outside influences alter the genome and affect how DNA is expressed via methylation.

Genetic Protections against HIV
AIDS is the final stage of HIV infection, which killed an estimated 2.1 million people in 2007, but some individuals have been found to be resistant to HIV/AIDS.
