Human Eye Color Genetics

For the past 6 decades, genetics has proven its ultimate importance in the fields of medicine, agriculture and law enforcement.

The milestone of DNA mapping has allowed scientists to develop treatments and medication for diseases, identify criminals and produce foods that are of health importance.

When coming to the human eye color, you might know all organisms encompassing plants, animals, and even humans have become subjects for studies in advancement of genetics. The following experiments require a basic knowledge of genetics and the terms associated with it.

Plant Genetics

The dawn of genetics started with Gregor Mendel’s experiment on pea plants. To be able to determine traits of pea plants genetically, you can re-create his original experiments. The California State Science Fair project number J1607 did this by propagating radishes instead of peas. You can also do this using a different plant of your desire. In their study, the shape of radishes is hypothesized to be influenced by environment upon growth rather than genetics.

Try to learn how horticulturists are able to develop disease- and drought-resistant plants by manipulating the plants’ genes. For plants that have many varieties, you can determine what traits have been bred into specific kinds of that specific plant by looking for its history. For example, you can search about tomatoes, which has been bred since time immemorial. Depending on the growth rate of the specific plant, studying them through propagation could take weeks to several months, thus making the process laborious and time consuming as such, but it is also rewarding.

Animal Genetics

As complicated as they are, animal genetics is hard to study and that’s why experiments on animal genetics normally require extensive research. If you want to learn about animal evolution and history, you can visit the Blast website and try to investigate what are the present-day relatives of the dinosaurs like the T-Rex. In the Science Buddies website you can determine the closest and the modern-day descendants of this dinosaur by comparing their protein sequences. This is easily done through a series of steps.

Making Your Own Genetic Characteristics Chart of Eye Color

If you are interested about human eye color genetics, most especially the genetics of rare eye color variation in your family; you can construct a genetics chart using the guide at the Science Buddies website. In the site you can also create pedigree for other varying characteristics of your family such as hair color, hitchhiker’s thumb, earlobe shape and many others. You can learn about other common traits that are inherited and usually vary. You can also learn how to diagnose certain genetic diseases. In reading about forensic investigations such as in murder cases, you will learn how DNA is used in law enforcement. For basic knowledge about diseases, it is also helpful to search about genetic factors (coupled with environmental factors as well) that could lead to development of certain diseases and disorders like cancer, diabetes or autism.
