December 3, 2014: My husband and I both have brown eyes. Mine are a lighter brown and his are dark brown. We have three children. One with green eyes (exactly the color of my sister's eyes), one with blue eyes, and one with dark brown eyes. My mom had green eyes, all the other grandparents had dark brown eyes. Where did the blue eyes come from?

August 27, 2014: I understand that both environmental and genetic factors affect a person's height. There is a belief among most people I've talked with that given that groups of ethnic peoples eat the same diet, that the different ethnic groups will have varying and predictable heights, based on their race. For example, my friends believe people of African descent will be tall as will Scandinavian descendants. However, they believe people of Asian descent will be shorter. I wonder if there is a section of DNA discovered that determines a person's height and if indeed a person's race is a good indicator of their height?

June 17, 2014: I have red hair and when got my wisdom teeth removed, my father told me that they had to use more than the regular amount of anesthetics usually needed. At first, I thought nothing of it. Then, when I later started a research paper on red hair, I found out that people with red hair generally need around 20% more anesthetics than people with other hair colors. Why is that? Is it because my MC1R gene is mutated, or is it something else completely.

March 6, 2014: I have been wondering this for a while since I've seen it pop up on various websites and forums…will red hair eventually go extinct? I honestly don't believe it will because it is recessive from what I know, and recessive genes don't up and disappear.

June 28, 2007: Leí su artículo titulado ¿Qué eso no hace tus ojos cafés azules? Los ojos azules son causados por cambios en el gen OCA2 y lo encontré muy interesante. Tengo otra combinación para agregar a la mezcla. ¿Puedes explicar la genética de una persona con un ojo azul y un ojo café? David Bowie es una de estas personas.
