My husband has bright orangey red hair with thick tight curls. I have stick straight Auburn hair (although as a child it went from a light strawberry blonde to a flaming red orange, slowly darkening to my auburn colour). I've heard that 2 redheads can only have redheaded children. So far, seems true - although all are different. Our first has soft curls, bright orange. Our second has straight, auburn. Our third really straight, light strawberry blonde. If we have more will they be redheads too? Why the variations in shades? Is it true 2 redheads can only have redheads?

I have red hair and blue eyes, both of my parents have blue eyes but light brown hair, My husband had dark brown hair and dark brown eyes, his parents both have dark brown hair and his mom has blue eyes and his dad has brown...my question is, if we have a child what are its chances of having blue eyes or red hair?

Is homosexuality an inborn, unchangeable part of us or can people actually "convert"? I think it is just the way I am but my classmates and some family members think otherwise. How can I convince them that this really is the way I am supposed to be?

How is it my grandmother smoked for nearly thirty years and is extremely healthy and looks great for 70? Whereas, my mother only smoked for 15 years before she had a stroke at the age of 38? I am curious since they are mother and daughter. Does genetics play a role in this circumstance?

I am a natural redhead since birth and recently read in the newspaper that redheads will be extinct by the year 2100. Is this a good possibility and if so could I preserve my eggs for the red hair gene?

My husband and I were wondering about the odds of making a red-headed child. He has very rich, very red hair. I on the other hand have had many hair colors and don't know what my genes are doing. From Birth to age 3, I had bright red hair. From about age 4 to 7 I had bleach blonde hair. After age 7 it turned sort of a dirty blonde, and has been ever since. My Dad had red hair till he was 30 years old then it turned dark brown. We are also very freckled people who sunburn very easily. I don't understand how hair color can change like that, and what genes I'm really carrying. If it helps, my mother has light brown hair and some freckles. Also, both my parents have green eyes, as do I. I hope you can at least explain the changing hair color phenomenon.

Has any progress been made in explaining eye colors other than brown, blue, and green? I've seen dozens of explanations of how the gey (EYCL 1) and bey2 (EYCL 3) genes are supposed to work, all with the disclaimer that this model doesn't explain colors such as hazel, grey, or black (not to mention violet, yellow, or very pale blue). Are the pigments responsible for some of these colors thought to be related to specific genes? Can there be more than two alleles for a gene, such as green, hazel, or blue? Has anybody studied the heritability of unusual eye colors?
