For each trait there are allele possibilities?
Yes, that is correct. Each trait is controlled by genes, and genes exist in different forms called alleles. For any given trait, an individual can have two alleles—one inherited from their mother and one from their father. These alleles can have different variations, resulting in different expression of the trait.
Based on his experiments Mendel concluded that each trait was controlled by two?
invisible "factors" - now called genes.
What controls a polygenic trait?
two or more genes
A trait seems to disappear when two different genes for the same trait are present?
recessive
What are polygentic traits?
Two or more genes control a trait.
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
What is a principle or law of heredity which states that for each trait there are two copies of the gene or genes that are responsible for the trait?
Mendel's Law Of Segregation
What is an organism with two genes for a trait called?
An organism with two like alleles for a trait is homozygous for that trait.

What trait disappears when two different genes for the same trait are present?
recessive trait
What is name of the two genes one on each chromosome of a pair that control the same trait are called?
They are called alleles. Each allele is a different form of the gene, and they can be dominant or recessive.

When a trait seems to disappear when two genes for the same trait are present?

How many genes determine an inherited trait?
Hello there! Traits controlled by two or more genes are for example skin color and height.
Two different genes for a certain trait?
Hybrid
