What are non-mendelian trait?
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
What are multiple allele traits?
A polygenic trait that require the additive effects of many alleles to be expressed. Height is an example of a polygenic trait. Or, a trait that has many alleles to fill the loci on chromosomes. Blood types are examples of this. A, B and O are all alleles that git the two chromosomal loci, but only any two at once whether homozygous or heterozygous.
Describe a trait that is controlled by multiple alleles?
Multiple AllelesThe term "multiple alleles" is used to describe when a trait is controlled by more than two alleles.This is simple and the only other thing to know is that even if a trait is controlled by more than two alleles each offspring still only inherits two. For example, a person cannot have ABo blood as it has more than two alleles.Blood type is the most common example of this as it does have three alleles, specifically "A", "B", and "o" blood types. Each of these controls the production of different antigenic substances on the surface of red blood cells. In this case both A and B are dominant and in the case of AB blood type codominance occurs. Meanwhile, type o blood is recessive. This blood type results in no antigens being produced. This is important in many medical situations, especially those involving blood transfusions, because the body of people receiving a blood transfusion rejects antigens that it is not familiar with and must therefore receive blood from people with the same blood type or with the o blood type because it does not produce any of the antigens that could be rejected, the reason for which it is considered the "universal donor" while AB is the "universal receiver" because it is familiar with both of the antigen types.

How many copies of alleles do organisms carry?
It depends on the organism but humans have two alleles.
How many alleles do people have for their charcteristics?
Humans typically have two alleles for each gene, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous), and they determine various characteristics. However, for traits controlled by multiple genes, the total number of alleles can vary significantly. Overall, the combination of alleles contributes to the diversity of traits in individuals.
How many alleles are there for blood type-?
There are three alleles for blood type: IA=Blood type A IB=Blood type B i=Blood type O The alleles for blood type A and B are codominant so when someone contains the IA and IB alleles, their blood type is AB.
How many alleles is a gene controlled by?
A gene is controlled by two alleles, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous), influencing the expression of the gene and determining an individual's specific traits.

In humans a trait can be determined by one pair of many pairs of?
alleles.
In humans a trait can be determined by one pair or many pairs of?
the minimum requirement is one pair but it could be more than one pair, an example can be found in human ABO blood groups. it an example of 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.
