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.

September 3, 2004: Hola, estoy tratando de entender más acerca del gen que es responsable de los hoyuelos en la mejilla y la barbilla hendida. Entiendo como una pareja Dd y Dd pueden tener un hijo que no tiene hoyuelos o hendidura, pero ¿es posible genéticamente que una pareja que no tiene hoyuelos en la mejilla o barbilla hendida tenga un hijo con estos dos rasgos? ¿Los hoyuelos en la mejilla y la barbilla hendida son causados por dos genes distintos o por el mismo gen? Veo que rasgos como el color de pelo, altura, y el color de ojos pueden ser determinados por varios genes que trabajan juntos pero ¿el rasgo de hoyuelos se comporta de esta manera o se trata simplemente de portar el gen responsable o no? ¿Han identificado o nombrado este gen? ¿Y las mutaciones, qué? ¿Pueden ser responsables por rasgos físicos o solamente de desordenes de salud? ¿Podrías hacerme el favor de contestar estas preguntas o dirigirme a alguien que las podría contestar?
