What is multiple alleles and codominant alleles?

What is multiple allele with example?

The major example of multiple allelism is ABO blood grouping in humans. Complete answer: Multiple alleles refer to the occurrence of three or more than three alleles for a particular gene. … Allele A codes for antigen A, Allele B codes for antigen B, and Allele O codes for the absence of antigen.

What are the two codominant alleles?

Codominance occurs when both alleles show dominance, as in the case of the AB blood type (IA IB) in humans. Furthermore, the human ABO blood groups represent another deviation from Mendelian simplicity since there are more than two alleles (A, B, and O) for this particular trait.

What is the term heterozygous mean?

(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

What are the examples of codominance?

Examples of Codominance:

  • AB Blood Type. People with this blood type have A and B proteins at the same time. …
  • Sickle-Cell Anemia. Sickle cell anemia is a disease where red blood cells become thin and stretched out. …
  • Horse color. The roan coat color of a horse is due to codominance. …
  • Flower colors.

Which statements describe Codominance?

Codominance involves the interaction of two alleles. Traits are neither dominant nor recessive. Both alleles, one from each parent, are expressed in offspring. Codominance involves the interaction of two alleles.
