基因的魔力
Have you ever wondered why you might look or act a bit like your parents? You may have heard the saying "Like father, like son". This isn't just because we grow up around our parents and learn from them. A big part is that we carry genes (基因) from them.
Our bodies have lots of genes. These genes are like a set of instructions that make us who we are. We get half of our genes from our mum and half from our dad. They decide things like the color of our hair and eyes, and even how tall we'll grow.
Genes also play a role in how smart we are. Women have two sets of certain genes related to intelligence, while men have one. This means kids are more likely to get their intelligence from their mums. But remember, being smart isn't all about genes. What we learn in school, from books, and through experiences is also very important.
Sometimes, some genes do not show up in our parents but can show up in us. Take eyelids (眼皮) for example. If both of your parents have double eyelids, but you have single eyelids, it's because they both carry the single-eyelid genes. When they pass their genes on to you, those single-eyelid genes become active.
In conclusion, genes from our parents are super important. They decide how we look and influence how smart we are. Learning about genes helps us understand why we are similar to our parents in some ways and different in others.
