are phenotypically expressed. They are expressed in homozygous form and in heterozygotes with the recessive allele. Recessive alleles are only phenotypically expressed in homozygous form. Consider two alleles for flower color, A and a, where A is dominant and expressed as red, and a is recessive and expressed as white. There are only three diploid genotypes possible for these alleles: AA Aa and aa.However, because A is dominant, the following phenotypes will be expressed for the following genotypes:
AA: red
Aa: red
aa: white
In eyes, it would be brown is dominant, and blue is recessive. Free earlobe allele is said to be dominant over the attached earlobe allele. When an organism has two dominant alleles for a trait, it is called homozygous dominant. Two recessive alleles for a trait is homozygous recessive.
Those would be called co-dominant alleles.
Gregor Mendel called them factors, or traits.
because it dominates the phenotype
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.

It is called alleles.
Dominant.
Homozygous
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
Those would be called co-dominant alleles.
Gregor Mendel called them factors, or traits.

.If this is for an answer in Horse Isle 2, the answer is dominant
