An allele is a variation or a type of gene
The dominant allele
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
A gene is a unit that determines heritable characteristics. An allele is one of the alternative versions of a gene for a character.
No, not exactly. They are different forms of the same gene.
An allele is a variation or a type of gene
The dominant allele
an allele is a gene that is the cause of hereditary variation
An allele is the different forms of a gene.
Do you mean allele? An allele is a different molecular form of the same gene.
The name for different forms of a gene is allele. >A< (A.S.Apex approved :P)

the alternative form of a gene is called an "allele."
An organism that is heterozygous for two traits means that it contains both the dominant allele and the recessive allele for both of the traits in question. For example, take a plant that produces peas. The gene that produces yellow seeds (denoted Y) is dominant, the gene for green seeds (y) is recessive. The gene that produces round seeds is dominant (R), the gene for wrinkled seeds (r) is recessive. So if this organism was heterozygous for both traits its genotype would be: Yy/ Rr Which means it has the allele for yellow seeds and the allele for green seeds (trait one), and also has the allele for round seeds and the allele for wrinkled seeds (trait two). Its phenotype (the traits it displays) will be yellow round seeds, as these are the dominant traits.
yes, different forms of a gene is called an allele. It was used in the early days of genetics to describe variant forms of a gene detected as different phenotypes
