History of genetics
Genetics is the study of how traits are passed down from parents to children, like how we inherit our eye color or hair type. The study of genetics goes back a long, long time in history. Here's a simplified explanation of how it all started:
Long ago, people noticed that animals and plants seem to resemble their parents. If a cow had a baby, that baby cow would look a lot like its mom or dad. This was the first clue that there was some kind of "inherited information" being passed down.
Years later, scientists started to study traits in animals more closely. For example, they noticed that some dogs would have long hair and others would have short hair. They started to understand that each trait was controlled by something called "genes" - which are like tiny instructions inside our bodies that tell us everything from what color our hair will be to how tall we will be when we grow up.
Over time, scientists began to really investigate these genes and how they work. They learned that genes are made up of long strings of code, called DNA. Much later, in the mid-1900s, researchers discovered that DNA is made up of four different building blocks, called nucleotides. These four nucleotides form a unique sequence in each gene, which ultimately determines what specific traits it controls. This is kind of like the letters in a recipe that tell us how to make a specific dish - each recipe has its own unique sequence of letters and words that tells us how to make it.
With the discovery of the structure of DNA and the underlying gene mechanisms, scientists were finally able to really understand the science of genetics. Nowadays, there is much research being done on this fascinating topic, with ongoing advancements and new discoveries constantly being made. It's a pretty cool subject to learn about!
