What traits are controled by a gene with multiple alleles?
Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
When both alleles contribute to the phenotype it is called?
PleiotropyPleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits, an example being phenylketonuria, which is a human disease that affects multiple systems but is caused by one gene defect.
What is an example of a human trait caused by a single gene with multiple alleles?
An example of a human trait caused by a single gene with multiple alleles is the ABO blood group system. This system is determined by the presence of different alleles at the ABO gene locus, specifically A, B, and O alleles. The combinations of these alleles result in four possible blood types: A, B, AB, and O, illustrating how multiple alleles can influence a single trait.
What are traits inherited by multiple alleles?
Traits inherited by multiple alleles are those that are controlled by three or more different forms of a gene (alleles) at a single locus. Examples include human blood type, where the ABO gene has three common alleles (IA, IB, and i), and coat color in rabbits, which is determined by four alleles of the C gene (C, cch, ch, and c).
What has multiple alleles?
more than two alternative form of a gene in a population occupying same locus on a chromosome or its homologous are called multiple alleles example--------blood group in human being -------- drosophila has 15 alleles for eye colour ---------- rabbit has 4 alleles for coat colour

What traits controlled by a gene with multiple alleles?
Some of the human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structures, etc. One notable and most common example of multiple alleles in humans would be of the blood groups.

How do you know that human height is not multiple alleles?
It is based on multiple alleles.
What three ways are human traits controlled?
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.
Which two terms best describe the inheritance of human blood types?
codominance and multiple alleles
What is the 4 exceptions to Mendel's principles?
The blood type in humans
If a trait has three different phenotypes the trait is inherited by?
Typically, traits with three different phenotypes are inherited by a single gene with multiple alleles. In this case, each allele controls a different phenotype. Examples of traits with multiple alleles include human blood type (A, B, O) and eye color (blue, brown, green).
What has multiple alleles?
more than two alternative form of a gene in a population occupying same locus on a chromosome or its homologous are called multiple alleles example--------blood group in human being -------- drosophila has 15 alleles for eye colour ---------- rabbit has 4 alleles for coat colour
Tell you about polygenic inheritance under genetics?
Polygenic inheritance refers to traits that are influenced by multiple genes, each contributing in a cumulative manner to the phenotype. These traits typically exhibit a continuous range of variation rather than distinct categories. Examples include human height and skin color, which are controlled by the interaction of multiple genes. Polygenic traits are also influenced by environmental factors.
