Can there be more than two alleles present for any given gene?

Although individual humans (and all diploid organisms) can only have two alleles for a given gene, multiple alleles may exist in a population level, and different individuals in the population may have different pairs of these alleles.

Can a gene have 4 alleles?

A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual.

How many alleles can a gene have?

Genes can have two or more possible alleles. Individual humans have two alleles, or versions, of every gene. Because humans have two gene variants for each gene, we are known as diploid organisms. The greater the number of potential alleles, the more diversity in a given heritable trait.

What happens if there are more than two alleles?

Traits controlled by more than two alleles have multiple alleles. Although any one person usually has only two alleles for a gene, more than two alleles can exist in the population’s gene pool. Theoretically, any base change will result in a new allele. … This is common in collagen genes, for example.

How many alleles for a gene can a person have Why?

Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene.
