With multiple alleles, that means there are more than two phenotypes available depending on the dominant or recessive alleles that are available in the trait and the dominance pattern the individual alleles follow when combined together.
What are the multiple alleles?
Alleles are described as a variant of a gene that exists in two or more forms. 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. … These three or more variants for the same gene are called multiple alleles.
What are the characteristics of multiple alleles?
Characteristics of Multiple Alleles:
- The study of multiple alleles may be done in population. …
- 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.
What are multiple alleles explain with example?
multiple alleles Three or more alternative forms of a gene (alleles) that can occupy the same locus. … For example, the ABO system of blood groups is controlled by three alleles, only two of which are present in an individual.
What are multiple alleles answer?
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.
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.
Why do multiple alleles occur?
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 a multiple allele trait in biology?
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.
Where are multiple alleles present?
Multiple alleles are present at the same locus as one type of chromosomes. The pairs of genes occupying a specific spot called locus on a chromosome are known as alleles.
What are multiple alleles quizlet?
Terms in this set (5)
Multiple Alleles. – When three or more alleles control a trait. Example. Blood Types in humans.
What are the three alleles responsible for ABO blood system?
The ABO locus has three main allelic forms: A, B, and O. The A and B alleles each encode a glycosyltransferase that catalyzes the final step in the synthesis of the A and B antigen, respectively.
Which of the following is a good example of multiple allele?
ABO blood group system provides a good example of multiple alleles.
