Can one gene have multiple alleles for certain traits?

Each gene is inherited in two alleles, i.e., one from each parent. Thus, this means there would also be having two different alleles for a trait. … Although humans (and all diploid organisms) can have only two alleles for any given gene in genetics, multiple allele traits may exist at the population level.

Can a gene have multiple alleles?

When the copies of a gene differ from each other, they are known as alleles. A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual.

Can a trait have more than two alleles?

Multiple Allele Traits

The majority of human genes are thought to have more than two normal versions or alleles. Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type.

How many alleles or genes do you have for a single trait?

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.

What traits have multiple alleles?

The best characterized example of multiple alleles in humans is the ABO blood groups, discussed in the Non-Mendelian Inheritance concept. Other human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structures, etc.

How are the alleles of a gene different from each other?

Alleles of a particular gene differ from each other on the basis of certain changes i.e. mutations in the genetic material segment of DNA or RNA. Different alleles of a gene increases the variability or variation among the organisms.

When there are 2 alleles for a gene and both make a protein product the alleles are said to be?

Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent.

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.

Can a trait be both polygenic and have multiple alleles?

Both multiple alleles and polygenic traits are the examples of non-Mendelian inheritance patterns. More than two factors are involved in the determination of a trait in multiple alleles and polygenic traits.

What are multiple alleles can a person have more than two alleles for a single gene explain your answer?

multiple alleles Three or more alternative forms of a gene (alleles) that can occupy the same locus. However, only two of the alleles can be present in a single organism. For example, the ABO system of blood groups is controlled by three alleles, only two of which are present in an individual.

Do alleles determine traits?

An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These DNA codings determine distinct traits that can be passed on from parents to offspring through sexual reproduction.

Are attached earlobes rare?

Attached earlobes are not rare but are also not commonly found. Earlobes of such type are small in size and are attached directly to the side of the head. … The recessive allele is expressed to form an attached earlobe.

Why does an individual always have only two alleles for a given gene?

Since diploid organisms have two copies of each chromosome, they have two of each gene. Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other.
