alleles are an expression of a gene given in chromosomes, which is coded by DNA, which in turn is made by the ribosomes , which in turn is made up of proteins.
Short answer: they are made up of proteins.

Compare homozygous alleles to heterozygous alleles?
When the alleles are identical, the individual is homozygous for that trait. While if the pair is made of two different alleles.
What type of alleles mask recessive alleles?
Dominant alleles :-)
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What term describes a pair of alleles that are the same?
Alleles that are the same = homozygous Alleles that are different = heterozygous
When more than two different alleles control a trait?
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
Compare homozygous alleles to heterozygous alleles?
When the alleles are identical, the individual is homozygous for that trait. While if the pair is made of two different alleles.
How alleles and genes related?
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
Are new alleles made by natural selection?
No - natural selection does not create new alleles. Variation in alleles needs to exist in the population in order for natural selection to occur. Natural selection will involve the change in allele frequencies over time, but it does not create new alleles. New alleles are the result of mutations.
What term defines a gene made up of two alleles?
Heterozygous
What term defines a gene made of two different alleles?
Heterozygous
What term defines a gene made up of two diffrent alleles?
Heterozygous
What term define a gene made up of two different alleles?
Heterozygous
Genotype made of two different alleles?
Homozygous
What type of alleles mask recessive alleles?
Dominant alleles :-)
What is Probability of a gamete getting one of a parents two alleles of a gene?
50% as there are two alleles per gene and four gametes are made from every undeveloped sex cell.
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What term describes a pair of alleles that are the same?
Alleles that are the same = homozygous Alleles that are different = heterozygous
