In the case of multiple alleles, one trait is governed by more than two alleles. One example is the human ABO blood group. There are three alleles, A, B, and O. A person can, however, only inherit two of the three alleles.

When than two 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.


When more than two different alleles control a trait?

This phenomenon is known as multiple allelism, where there are more than two different variations of a gene (alleles) that can affect a single trait. In this case, individuals can inherit one of several possible alleles for the trait. Examples include the ABO blood group system in humans, where there are three alleles (IA, IB, i) that determine a person's blood type.


A trait controlled by four alleles is said to have?

A trait controlled by four alleles is said to have multiple alleles.


What is a trait controlled by three or more alleles have?

multiple alleles


What is the likelihood of inheriting a genetic trait with more than two alleles, and how does the presence of multiple alleles impact the expression of the trait?

The likelihood of inheriting a genetic trait with more than two alleles is rare. When a trait has multiple alleles, it can result in a wider range of possible expressions of that trait. This can lead to more variation in the phenotype among individuals who inherit different combinations of alleles for that trait.


What are more than two alleles that exist in a population for a particular trait?

What is the condition whereby a trait is determined by three or more alleles called?

The condition whereby a trait is determined by three or more alleles is called multiple allelism. Multiple alleles refer to the presence of more than two alleles of a gene within a population. This can result in various combinations of traits and phenotypes.


In ------ these are more than two alleles possible for a trait?

In multiple-allele inheritance, there are more than two alleles possible for a trait. This means that instead of just two versions of a gene (alleles), there can be multiple variations that influence the trait in different ways. Examples of traits with multiple alleles include blood type in humans and coat color in rabbits.


The number of possible phenotypes for a given trait depends on how many what control the trait?

The number of possible phenotypes for a given trait depends on how many genes control the trait. Each gene may have multiple alleles that can interact to produce different phenotypes. Additionally, environmental factors can also influence the expression of these genes, further increasing the diversity of possible phenotypes.


How is a trait that is determined by multiple genes different from one that is determined by multiple alleles?
