What are traits controlled by multiple alleles?
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.
Multiple Allele Traits.
|Genotype||Phenotype (blood type)|
What is multiple alleles explain with the help of an example?
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 definition?
: an allele of a genetic locus having more than two allelic forms within a population.
Why is it advantageous to have 2 alleles per trait?
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. … This means that if a pea plant has two red alleles, its flowers will be red.
What are examples of multiple alleles?
Two human examples of multiple-allele genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes.
What are multifactorial traits?
What is multifactorial inheritance? Multifactorial inheritance is when more than one factor causes a trait or health problem, such as a birth defect or chronic illness. The main factor is genes. But the cause includes other factors that aren’t genes, such as: Nutrition.
Which of the following traits is controlled by multiple alleles in humans quizlet?
Human blood type is controlled by a gene with multiple alleles. There are four main blood types: A,B,AB, and O. Three alleles control the inheritance of blood types. The allele for blood type A and the allele for blood type B are codominant.
