Hi,
You're welcome. Doing so was interesting.
Well, we cannot argue with reality, especially if it has been checked carefully.
We've all heard of birth defects. They are caused by several environmental factors such as radiation or exposure to chemicals.
Sometimes small errors occur in the genetic code that controls our physical traits. I suspect that such an error occurred in the case of two different ears and two different-colored eyes.
Maybe one of you (students) might like to find out if such genetic defects do occur. There are online experts who might help. Can you find them?
