Yes which ever of the two alleles is dominant, then the phenotype will take the one of the dominant. they can be codominant, so in that case, you might be able to produce 4 phenotypes. it depends if the two alleles create 4

∙ 11y agoYes, it is. Take blood types for example, a person can be AO with the O allele being recessive or AA and they both have type A blood for their phenotype

A trait controlled by four alleles is said to have?
A trait controlled by four alleles is said to have multiple alleles.
You are looking at four tall pea plants What are their phenotypes and genotypes?
tall; Tt or TT
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 are non-mendelian trait?
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
How many of the possible types of offspring had the same genotype as the parents?
Use a punnet square it may be a little tricky though.Just remember which letter is dominant and which one is recessive.heterozygous and Homozygous.
Is it possible for two alleles to produce four phenotype?
yes
Is it impossible for two alleles to produce four phenotypes?
This would depend upon how they are expressed. Are we talking dominant, codominant, or recessive? Then there are genes thought to be fine tuned by environmental factors.
What are multiple-allele traits?
Traits governed by multiple alleles are controlled by three or more alleles, rather than two. An example in humans is the ABO blood group system. There are three alleles in the ABO blood group system, IA, IB, IO. These three alleles can produce six genotypes, AA, AO, BB, BO, AB, OO. These genotypes can produce four different phenotypes, A (genotypes AA or AO), B (genotypes BB or BO), AB, (genotype AB) and O (genotype OO).

A trait controlled by four alleles is said to have multiple alleles.
Why is blood type an example of multiple alleles?
Multiple Alleles:The ABO blood group in humans is determined by multiple alleles of a single gene. There are four possible phenotypes for this character: A person's blood may be either A, B, AB, or O. These letters refer to two carbohydrates--A and B-- that may be found on the surface of red blood cells. A person's blood cells may have carb. A (type A blood), carb B (type B blood), both (type AB), or neither (type O).The four blood groups result from various combinations of three different alleles for the enzyme (I) that attaches the A or B carb. to red blood cells. The enzyme encoded by the IA allele adds the A carb, whereas the IB carb adds the B carb. The enzyme encoded by the iallele adds neither A nor B. Because each person carries two alleles, six genotypes are possible, resulting in four phenotypes. The IA and the IB alleles are dominant to the i allele. They are codominant; both are expressed in the phenotype IAIB heterozygous, who have type AB blood.Source: Campbell, Neil and Reece, Jane. "AP Edition Biology: Seventh Edition.''
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 is the phenotype of all four offspring's?
Generally, if the parents are heterozygous and one allele is dominant over the other there are only 2 phenotypes and 3 genotypes. Parents Aa can produce AA, Aa and aa offspring. If the heterozygous individuals have an intermediate phenotype, then three genotypes and 3 phenotypes are possible. If 2 traits are being studied using heterozygous parents AaBb then the possible Genotypes are AABB, AABb, AAbb, AaBB, AaBb, Aabb, aaBb, aaBB, aabb which is nine genotypes. But there are 4 phenotypes. AABB AABb AaBB AaBb are phenotypically the same. aaBb, aaBB are phenotypically the same. Aabb, AAbb are phenotypically the same. aabb
How many alleles are there for radish shape?

Is one blood group more dominant than another?
Genotypes, Phenotypes, and frequencies in the ABO blood-typing systemGenotype Blood Type A Antigen present B Antigen Present Frequency exampleIAIA or IAi A + - 41IBIB or IBi B - + 11IAIB AB + + 4ii O - - 44Among the six possible genotypes, there are four distinguishable phenotypes- the A,B,AB and O blood types. In this system, the IA and IB alleles are codominan, since each is expressed equally in the IA IB heterozygotes, and the i allele is recessive to both the IA IBalleles.Principles of Gentics Snustad.Simmons

What are the four major hypotheses mendel developed?
Phenotypes are expressed as alleles, which are different forms of a certain physical feature This expression can be dominant: there is a higher preference for this feature being expressed OR recessive: there is a lower incidence of this feature being expressed Principle of segregation: Alleles from the parents sepatrate and only one allele is passed on from each parent to the offspring Independent assortment: Different pairs of alleles are passed on to offsprings independently of each other
Why does height in humans have such a wide variety in phenotypes?
Because Height is controlled by at least four genes
