What are multiple alleles What is an example in humans?

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 meant by multiple allele?

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

What are multiple alleles give an example class 12?

Multiple alleles refer to the occurrence of three or more than three alleles for a particular gene. Alleles are different or contrasting forms of a gene. For example, for the gene encoding for height, one allele can be for tallness, whereas the other can be for dwarfness.

Is eye color an example of multiple alleles?

Yes, eye colour is an example of multiple alleles. They are more than two alleles encoding for the same.

What are multiple alleles Ncert?

Answer: More than two alternative alleles of a gene are known as multiple alleles in a population occupying the same locus on a chromosome or its homologue.

Is blood type an example of multiple alleles?

An excellent example of multiple allele inheritance is human blood type. Blood type exists as four possible phenotypes: A, B, AB, & O. There are 3 alleles for the gene that determines blood type.

What are multiple alleles in 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.

What are multiple allele traits?

The study of multiple alleles may be done in population. ADVERTISEMENTS:

Multiple alleles are situated on homologous chromosomes at the same locus.

There is no crossing over between the members of multiple alleles.

Multiple alleles influence one or the same character only.

Multiple alleles never show complementation with each other.

What does multiple alleles mean?

The phrase “multiple alleles” in biology refers to a series with at least three allelic or alternative forms of a particular gene, with only two that are able to exist in a diploid individual. There are two alleles present in an individual: a paternal and a maternal allele.

What is the difference between an allele and a gene?

Gene is the main component of a DNA strand and it contains the necessary genetic information about the organism.

The purpose of a gene is to define the genetic traits of an organism.

Genes are responsible for the genotype of the organism.

Individual Genes are known as Alleles.

What are facts about allele?

Dominance. In a heterozygote the effect of one allele may completely ‘mask’ the other.

Sex linkage. Genes on the sex chromosomes are said to be sex linked.

Different alleles at a locus. There are three ways alleles at a locus may differ. Alleles differ by origin if they come from the same locus on different chromosomes.
