What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
What is the minimum number of alleles that may be present for a given genotype controlled by a single gene?
The minimum number of alleles that may be present for a given genotype controlled by a single gene is one. This occurs in the case of a homozygous genotype, where an individual carries two identical alleles for that gene. However, if considering a heterozygous genotype, two different alleles would be present. Thus, for a single gene, the minimum is one, while the maximum can be two in diploid organisms.
What trait is controlled by a gene with multiple alleles?
A trait controlled by a gene with multiple alleles is one where more than two variations of a gene exist within a population, influencing the phenotype. A classic example is the ABO blood group system in humans, where the gene has three alleles: A, B, and O. These alleles can combine in different ways, resulting in four possible blood types: A, B, AB, and O. This genetic complexity allows for a greater diversity of traits within a species.
What are traits inherited by multiple alleles?
Traits inherited by multiple alleles are those that are controlled by three or more different forms of a gene (alleles) at a single locus. Examples include human blood type, where the ABO gene has three common alleles (IA, IB, and i), and coat color in rabbits, which is determined by four alleles of the C gene (C, cch, ch, and c).
What the function of a homozygous?
A homozygous individual carries two identical alleles for a specific gene. This often leads to a consistent expression of the trait controlled by that gene. Homozygosity can have different impacts depending on whether the alleles are dominant or recessive.
What trait is controlled by a gene with multi alleles?
The ABO blood groups in humans are controlled by multiple alleles.
What is a gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
Blood types in humans are an example of traits controlled by?
Multiple alleles
What is a trait controlled by a single gene that has two alleles?
One example of a trait controlled by a single gene with two alleles is flower color in snapdragons. The gene responsible for flower color has two alleles: one for red flowers and one for white flowers.

How many alleles are typically present in a gene?
Typically, there are two alleles present in a gene, one inherited from each parent.
How many alleles can be in each gene?

A gene is said to have multiple alleles if it has more than how many alleles?
A gene is said to have multiple alleles if it has more than two different forms or variants (alleles). This means there are more than two variations of the gene present in a population.
