Yes, you have. Ephelis is just a type of freckle.
The poster that caught my eye was about ephelis. I had no idea what it was until the student told me that I did know what it was. The title was the most eye-catching part of it. It pulled me in like none of the other posters there. Its layout was pretty nice too. It was easy to read and had a pedigree chart that was very interesting.
The poster was explaining ephelis and two of the genes that were related to ephelis. One of the genes was directly related to the production of melanin in the body. This was important because freckles are directly related to melanin. So much so that a high concentration of melanin in one area of the skin causes the skin to appear freckled. This gene was called MC1R (Melanocortin 1 receptor). Not only was this gene related to freckling and melanin, but it was also related to hair color. The other gene was indirectly related to a specific type of melanoma that was deadly to the body.
I thought this was a very successful poster attempt. It had an appropriate amount of visuals, but they could have added more. The pitch was very well said and it seemed like the student knew exactly what he was talking about. It would have been nice if he could have explained the pedigree chart to me; however, I did learn something very important from this poster, apart from all the valuable scientific information it presented in an organized fashion.
I did know what ephelis was.
It’s great that you remembered the details, but also had that constructive criticism about not having the pedigree chart explained. My rule of thumb is, if you can’t or won’t explain it, don’t put it in the poster.
