Interactive, plain-language tools that make DNA, inheritance, and genetic risk easier to understand. Learn the basics, then try the tools.
Educational tools, not medical advice
A quick introduction before you begin. These ideas appear throughout the tools below.
DNA
DNA is the set of instructions inside every cell that tells the body how to grow and work.
Genes
Genes are short sections of DNA. Each gene carries the instructions for one particular trait or task.
Chromosomes
Chromosomes are tightly packed bundles of DNA. Most people have 23 pairs, one of each pair from each parent.
Inheritance
Inheritance is how genes pass from parents to children, which is why traits and some conditions run in families.
Dominant genes
A dominant gene shows its effect even when only one copy is inherited, from just one parent.
Recessive genes
A recessive gene usually shows its effect only when two copies are inherited, one from each parent.
Carriers
A carrier has one copy of a recessive gene but no symptoms. Carriers can still pass the gene to their children.
Each tool is a self-contained educational experience. Open one to see how it works.
Visualise how a recessive condition may pass from parents to children.
Understand why shared ancestry can raise the chance that both parents carry the same recessive variant.
Explore where evidence about inherited genetic disorders has actually been documented across Pakistan, and where the data is still missing.
See how possible allele combinations connect to inheritance probabilities, through the calculator or an educational scenario.
See how a change connected to a specific gene can affect biological function and contribute to a genetic disorder.
A recommended order, but you can explore in any order you like.
