They can be both. Wikipedia provides small descriptions of some of the different types of mutation
Green and blue eyes are caused by the same gene. So neither would be dominant over the other.
Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.
If by "all dominant phenotypes" you mean the parents are homozygous, then no. AA x AA will never yield a gamete with AA But if you're talking about heterozygous chromosomes Aa x Aa, then yes
dominant-appears in first generation recessive-seems to dissapear
yes they are recessive
Well, black hair is the most dominant, but if you were comparing, say, blond hair to brown hair then the brown hair would be dominant. I am studying this for collage right now so I an pretty sure this is right, if it's not i am so doomed :0!!! lol! hope that helped, Aquilo
Brown eyes are dominant. That's why more people have brown eyes then hazel or blue or green.
With brown eyes, they are recessive.
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.

There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
Recessive gene is one which is supressed and do not show their characteristics and dominant gene is one which show their characteristics for example if a father has brown hair and mother has black hairs and if their son has black hair then in this case gene which has characteristics of black is dominant and the other which has characteristics of brown colour is recessive
A dominant trait occurs when either both alleles are dominant or one allele is dominant and the other is recessive. This is because a dominant allele overpowers a recessive allele. In order to have a recessive trait both alleles must be recessive.
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
It depends what area you are talking about. If its in Europe then maybe blue eyes, or if its in India then probably brown eyes. In the whole world it is brown eyes.
Green and blue eyes are caused by the same gene. So neither would be dominant over the other.
