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 is a multiple allele?
: an allele of a genetic locus having more than two allelic forms within a population.
What are multiple alleles answer?
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. Features of multiple alleles. The same genes have more than two alleles. All multiple alleles in homologous chromosomes occupy the respective loci.
Which one of the following is an example of multiple allele?
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.
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.
What is allele explain?
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.
How many types of alleles are there?
An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.
