What is interesting about genetics?

There are thought to be about 3 billion base pairs in the human genome. Only about 3\% of the DNA actually codes for genes; the rest is often called “non-coding DNA” because its function is unknown. A genome is the total compliment of genes for an organism. There are approximately 23,000 genes in the human genome.

Why is it important to learn about genetics?

Genetics research studies how individual genes or groups of genes are involved in health and disease. Understanding genetic factors and genetic disorders is important in learning more about promoting health and preventing disease.

What should I know about genes?

A gene is a short section of DNA. Your genes contain instructions that tell your cells to make molecules called proteins. Proteins perform various functions in your body to keep you healthy. Each gene carries instructions that determine your features, such as eye colour, hair colour and height.

14 strange facts about your DNA

  • Around 5-8\% of your DNA isn’t human – it’s viral DNA.
  • We share 96\% of our DNA with primates such as chimpanzees, gorillas and orangutans.
  • Around 99.9\% of the DNA in all humans is identical.
  • Humans have approximately 10 trillion cells.

Why do siblings look alike?

After all, kids get their genes from the same parents. But brothers and sisters don’t look exactly alike because everyone (including parents) actually has two copies of most of their genes. Parents pass one of their two copies of each of their genes to their kids. Which copy a child gets is totally random.

Who discovered genetics?

Gregor Mendel
Gregor Mendel: the ‘father of genetics’

How do I know my genetics?

Genetic tests are done using a blood or spit sample and results are usually ready in a few weeks. Because we share DNA with our family members, if you are found to have a genetic change, your family members may have the same change.

Do we understand all DNA?

We do not know what most of our DNA does, nor how, or to what extent it governs traits. In other words, we do not fully understand how evolution works at the molecular level.
