Which is a mendelian trait?
A trait controlled by many genes
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 is the difference between a single gene and a polygenics trait?
A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
How many alleles are there for a Mendelian traits?

What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
How many alleles for a trait are there?

When a trait has more than two alleles, how is that trait inherited?
Not sure if I understand the question correctly... but any single set of normal allelic pairs would be inherited according to standard Mendelian ratios, but the phenotypic expression would be more complex and would not reflect Mendelian ratios there might be an additive effect of having alleles A, B C as opposed to the recessive complement a, b, c - this would pertain to traits as drosophila wing span, all three dominant alleles result in larger wingspan but this is often complicated by the presence of alleles which can "knock out" the effect of entire complements of alleles, effectively cancelling out expression no matter how many other pro-length alleles are present... it is difficult to talk about in the abstract... :)
What determines a Mendelian trait?
Chromosomes do not have a sex/gender but determine it. In humans, females have two X chromosomes (XX) and males have an X and a Y chromosome (XY).
What describes the mating of organisms that have different homozygous alleles for a single trait?
The mating of organisms with different homozygous alleles for a single trait is referred to as a monohybrid cross. In this scenario, one parent possesses two dominant alleles (homozygous dominant), while the other has two recessive alleles (homozygous recessive). The offspring produced from this cross will be heterozygous, displaying the dominant trait, while the recessive trait will not be expressed in the phenotype. This type of cross is often used to illustrate basic principles of Mendelian inheritance.
How many alleles for one trait can an individual have?
An individual can have a maximum of two alleles for one trait, as they inherit one allele from each parent. These alleles can be the same (homozygous) or different (heterozygous) for a specific trait.
Why does an organism have one factor for a dominant trait and one factor for a recessive trait?
Organisms have two factors (alleles) for a trait because they inherit one from each parent. Dominant traits are expressed when at least one dominant allele is present, while recessive traits are only expressed when both alleles are recessive. This is known as Mendelian inheritance.
What is a non mendelian trait?
A trait with no clearly dominant allele.
