Frequent question: What is multiple allele and give any one example?

In biology, multiple alleles are three or more alleles for a particular gene. Multiple allelism (biology definition): The condition of the presence of multiple alleles. An example of multiple alleles is the ABO blood group system in humans.

What is meant by multiple allele?

: an allele of a genetic locus having more than two allelic forms within a population.

What is an allele explain Giving one example?

Alleles are different forms of the same gene. … An example of alleles for flower color in pea plants are the dominant purple allele, and the recessive white allele; for height they are the dominant tall allele and recessive short allele; for pea color, they are the dominant yellow allele and recessive green allele.

What are multiple alleles Class 12?

Category : 12th Class. More than two alternative forms (alleles) of a gene in a population occupying the same locus on a chromosome or its homologue are known as multiple alleles.

Which of the following is an example of multiple allele?

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.

What is allele with Example Class 10?

Alleles are a pair of genes that occupy a specific location on a particular chromosome and control the same trait. … A pair of alleles determine the same trait, for example, eye color; one allele codes for black eyes, and another allele codes for brown eyes. All the alleles found in an organism make up the genotype.

What is the example of allele?

Various Types Alleles Paternal vs maternal Dominant vs recessive
Examples Eye color, hair color, skin pigmentation Blue eyes, brown hair, dark skin

WHAT IS A allele Class 10?

An allele is an alternative form of a gene. It is located at a specific position on a specific chromosome. These can be passed on from parents to offspring through sexual reproduction.

What is multiple alleles explain in brief with suitable example?

In humans, the ABO blood groups are controlled by a gene called gene ‘I’. It has three alleles, namely IA, IB and i. Dominance: The alles IA and IB are dominant over the allele i. … Multiple allelism: Since the blood grouping is governed by more than two alleles, it is a good example of multiple allelism.

What are multiple alleles in zoology?

Multiple alleles exist in a population when there are many variations of a gene present. In organisms with two copies of every gene, also known as diploid organisms, each organism has the ability to express two alleles at the same time.

What is multiple alleles and codominant alleles?

Whenever a given trait has three or more different alleles, we say that the trait has multiple alleles. … These three alleles that constitute the ABO blood group trait observe a pattern of inheritance called codominance (co-dominance).

Is skin color an example of multiple alleles?

Polygenic Inheritance: Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three “dominant” capital letter genes (A, B and C) control dark pigmentation because more melanin is produced.
