They don't. Each parent should only have two.. One from each of their parents.

What are pure alleles?
Alleles come in pairs. Organisms inherit one allele from each parent organism with sexual reproduction. If the alleles are the same, they could be said to be pure alleles. The science term is monozygous.
How many alleles for a trait are passed down from each parent?
There are three common Blood type alleles: A, B, and O. We all have two alleles, one inherited from each parent. The possible combinations of the three alleles are: OO; AO; BO; AB; AA; BB.
How many alleles for one trait are normally found in the genotype of an organism?
Typically, an organism will have two alleles for one trait in its genotype, one inherited from each parent. These alleles can be the same (homozygous) or different (heterozygous).
The inherited combination of alleles is known as the offspring's?
The inherited combination of alleles is known as the offspring's genotype. It determines the genetic makeup of an individual based on the alleles inherited from each parent. The genotype influences the phenotype, or the observable traits of an organism.
Organism possessing two identical genes for a trait is said to be?
Homozygous. This means that the organism has two identical alleles for a specific trait, one inherited from each parent. This can result in either a dominant or recessive expression of the trait, depending on the specific alleles involved.
Why does each parent organism in the f1 generation have four alleles listed in figure 6.17?
Each parent has two genes with two alleles so there are four alleles.
What are pure alleles?

Mendel's law of segregation states that an organism inherits two alleles for any given trait one from each parent?
Mendel's law of segregation states that each organism carries two alleles for a trait, one from each parent, and during gamete formation, these alleles segregate randomly into separate gametes. This results in each gamete carrying only one allele for a given trait.
What are alleles and how are they inherited from parent cells?
Alleles are alternative forms of a gene that can occupy the same position on a chromosome. When an organism inherits alleles from its parents, one allele is typically inherited from each parent. This process occurs during sexual reproduction, where each parent contributes one allele to the offspring.
Organism that has two diffrent alleles for a single trait?
An organism that has two different alleles for a single trait is called heterozygous. This means that the organism inherited different versions of the gene responsible for that trait from each parent.
The inherited combination of alleles is known as the offspring's?
The inherited combination of alleles is known as the offspring's genotype. It determines the genetic makeup of an individual based on the alleles inherited from each parent. The genotype influences the phenotype, or the observable traits of an organism.
What percent of each alleles does each parent contribute to their offspring?
50% from each parent: one allele in each gene, each parent, for a total of two.
An organism that receives the same genetic traits from each parent?
An organism that receives the same genetic traits from each parent is called homozygous for that particular trait. This means that both alleles inherited from the parents are the same. It often results in a consistent expression of that trait in the offspring.
What is the difinition of alleles?
An allele is a form of a gene. For example, the allele B may lead to black fur and the allele b may lead to white fur. Both B and b are alleles for fur colour.In general notation, dominant alleles are written with a capital letter (eg. B, T, P) and recessive alleles are written with a lower case letter (eg. b, t, p). A person will have two alleles (one from each parent) for every gene. Dominant alleles are expressed over recessive alleles.
What is genetic relationship between generations?
Each new generation inherits alleles from the previous generation.
What are genetics material for a trait from each parent called?
alleles
