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.
What is a gene that has 3 or more alleles for a single trait?
An example of a gene with three or more alleles for a single trait is the ABO blood group gene. This gene has three main alleles - A, B, and O - which determine blood type. The different combinations of these alleles result in the various blood types (A, B, AB, and O) observed in humans.
How many genetically different types of sperm could an animal that is heterozygous-dominant for one trait produce and Acirc and nbsp and Acirc and nbsp and Acirc and nbsp and Acirc and nbsp and Acirc?
An animal that is heterozygous-dominant for one trait can produce two genetically different types of sperm. This is because it has two different alleles for that particular trait, and each sperm will randomly receive one of the two alleles during meiosis.
How many dominant alleles are required in a genotype to show the dominant phenotype?
If the allele is dominant, you only need one copy for it to be expressed in the phenotype (you have TWO alleles for each trait) If the allele is dominant, you only need one copy for it to be expressed in the phenotype (you have TWO alleles for each trait)
The blood types A B AB and O are the result of what inheritance multiple allelic polygenic or simple dominant?
The blood types A, B, AB, and O are determined by multiple alleles. These alleles exist at the same gene locus on chromosome 9 and interact to create the different blood types. Each individual has two of these alleles, resulting in the ABO blood type system.

What is an example of a trait inherited by multiple alleles?
The best example possible; blood types!
The blood type trait which is controlled by more than two alleles for a given gene and therefore is called?
The blood type trait that is controlled by more than two alleles for a given gene is known as the ABO blood group system. It involves three alleles: A, B, and O, which determine blood types A, B, AB, and O. This system results in four possible blood types due to the combination of these multiple alleles.

An example of a gene with three or more alleles for a single trait is the ABO blood group gene. This gene has three main alleles - A, B, and O - which determine blood type. The different combinations of these alleles result in the various blood types (A, B, AB, and O) observed in humans.
Are dominant alleles naturally better for an organism?
No, recessive alleles are equally likely to be inherited (if your dealing with only those two types of alleles). BUT, dominant alleles are the ones that show up. That is precisely why they are called dominant. Compared to recessive alleles, dominant ones will overrule the others, making it the one inherited.
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.
How many genetically different types of sperm could an animal that is heterozygous-dominant for one trait produce and Acirc and nbsp and Acirc and nbsp and Acirc and nbsp and Acirc and nbsp and Acirc?
An animal that is heterozygous-dominant for one trait can produce two genetically different types of sperm. This is because it has two different alleles for that particular trait, and each sperm will randomly receive one of the two alleles during meiosis.
What is the allele which is overuled?
The two types of alleles are dominant and recessive. The recessive allele will still be present but the recessive trait is not usually seen. However, is not always overruled. In the cases of codominance and incomplete dominance, the recessive trait still shows through some of the dominant one.
How many dominant alleles are required in a genotype to show the dominant phenotype?
If the allele is dominant, you only need one copy for it to be expressed in the phenotype (you have TWO alleles for each trait) If the allele is dominant, you only need one copy for it to be expressed in the phenotype (you have TWO alleles for each trait)
What do dominant and recessive alleles have in common?
Alleles are different types of a gene. Each gene controls a characteristic and they is usually a recessive allele and a dominant one. The main similarity is that they both control a certain characteristic!
What is it called when two of a trait are both dominant at the same time?
Codominance. It's the case of AB blood types, for instance. Neither trait is dominant over the other, so both manifest.
What is it called when two forms of a trait are dominant at the same time?
Codominance. It's the case of AB blood types, for instance. Neither trait is dominant over the other, so both manifest.
