What are multiple alleles answer?

What are multiple alleles simple?

Multiple alleles is a type of non-Mendelian inheritance pattern that involves more than just the typical two alleles that usually code for a certain characteristic in a species. … Other alleles may be co-dominant together and show their traits equally in the phenotype of the individual.

What is multiple alleles explain with 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 do you mean by Polygenes?

A polygene refers to a group of genes that when expressed together produce a particular phenotype or trait. The trait produced is therefore a result of the expression of multiple genes. This type of trait is referred to as a polygenic trait. … Thus, polygenes allow a wide range of physical traits.

What do you mean by Pleiotropism?

Pleiotropism is the condition in which a single gene controls more than one phenotypic effect, that is completely unrelated. E.g.: Phenylketonuria. It is an autosomal recessive disorder affecting chromosome number 12.

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

What is multiple Allelism give its suitable example?

More than two i.e. three alleles governing the same character is known as multiple allelism. ABO blood grouping is a good example of multiple allelism ABO blood groups are controlled by the gene I.

Why is multiple allele trait described as such?

Traits controlled by more than two alleles have multiple alleles. Although any one person usually has only two alleles for a gene, more than two alleles can exist in the population’s gene pool. Theoretically, any base change will result in a new allele.

Which one of the following is an example of multiple alleles?

An example of multiple alleles is the ABO blood-type system in humans. In this case, there are three alleles circulating in the population.

What is multiple alleles PDF?

Multiple alleles can be defined as a series of forms of a gene situated at the same locus of homologous chromosomes. According to Mendel, each gene had two alternate forms or allele morphs are being dominant and the other being recessive.
