A dominate trait
A mutation can be either recessive or dominant depending on what trait it is.
Codominance is when 2 dominate genes appear in the phenotype of an organism. (some one else can tell you what dominate and recessive genes are)
Alleles are neither entirely recessive nor entirely dominate. An allele is any one of a number of alternative forms of the same gene on a chromosome.For example: say a flower only blooms either red or white flowers. There is a different allele for each color-- a red allele and a white allele. Now, one color may be dominate over the other recessive gene. For example, if the red color was dominate and the white color was recessive, then those certain alleles would be dominate and recessive, respectively. But alleles in general cannot be either recessive or dominate. It depends on the gene and it depends on the trait.
semi-dominant--semi-recessive
It depends on the "lenght" of your eyelashes. If you have long eyelashes than it is dominant. If you have short eyelashes than it is recessive.
