Which one of the following is a good 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 is multiple alleles give 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?

Multiple alleles among humans

When a trait has three or more distinct alleles, we refer to it as having multiple alleles inheritance. The human ABO blood type alleles/trait is an example of a trait with multiple alleles. Three distinct alleles exist: allele A (IA), allele B (IB), and allele i (IO or i).

Which is an example of multiple alleles quizlet?

What is an example of multiple alleles in the human body? Blood type. … -The Rh factor is a type of protein on the surface of red blood cells.

Which of the following is NOT example of multiple alleles?

Like ABO blood group, MN blood group also shows multiple allelism. Explanation: In MN blood group system there are only two alleles M and N which are codominant. Thus, this is not an example of multiple alleles but ABO blood grouping is.

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.

Is multiple alleles common in humans?

Although individual humans (and all diploid organisms) can only have two alleles for a given gene, multiple alleles may exist at the population level, such that many combinations of two alleles are observed. … An example of multiple alleles is the ABO blood-type system in humans.

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 does it mean to have multiple alleles quizlet?

Multiple Alleles. – When three or more alleles control a trait. Example. Blood Types in humans.

What are the possible alleles for blood groups?

The four main blood groups A, B, AB, and O are controlled by three alleles: A, B, and O. As humans are diploid, only two of these can be present in any one genotype. In other words, only two of these alleles are present at the same time in a person’s cell.
