Phenotype is the displayed traits of an individual that are based on the types of alleles at a gene locus. Genotype is the actual alleles present whether they are expressed or un-expressed.
For example: Offspring 1 is genetically AA agouti coloration or barred coat pattern
Offspring 2 is genetically aa sold color/no barring
Offspring 3 is genetically Aa agouti coloration or barred coat pattern
Offspring 1 and Offspring 3 are genetically different but visual appearance of both is the same. Only one A allele is required to produce this coat pattern. Unless there is a genetic test for Aa versus AA a breeding test using a known homozyous recessive individual will prove whether the individual will breed true or produce varied offspring.
Offspring 2 is genetically and phenotypically non-agouti and will breed true if bred to another non-agouti.

A trait that is masked by a dominant trait is called?
DNAactually it is not DNA at all, a dominant trait, masks a recessive trait.
Condition of being heterozygous for a recessive trait?
If you are heterozygous this means you carry both a dominant and recessive allele. if you are heterozygous for a recessive trait then you will have a dominant and recessive allele. example: let T represent tall and t represent short. a person with heterozygous for a recessive trait will have 'Tt'.
How do you write the genotype for a trait?
Genotypes are written differently depending on what gene you are referring to. A capital letter means that allele is dominant over an allele written with a lower case letter. For example B is dominant over b. Some genotypes are written using a superscript, such as IAIB for the genotype of a person with blood type AB. Or HbsHbs for a person with sickle cell anaemia (compared to HbSHbS for a person without sickle cell). In this case Hb stands for haemoglobin. Usually the letters chosen relate to the trait involved... for example, if talking about tall plants T would be used to represent the tall allele and t would represent the short allele.
The Hardy-Weinberg principle is written as the equation p2 2pq q2 1. What does p represent?
The frequency of the homozygous dominant genotype.
What does it mean if there is two different alleles for a trait?
The trait could show up in two different forms. Alleles are individual units that determine what trait will be expressed in an offspring. Alleles exist for most traits such as hair color or wing size. Having two alleles simply means that the trait can be expressed in different variation. One trait can have several different alleles.
What is the genetic composition determining a trait?
Genotype is the genetic makeup of a trait.
Is the genotype of the individual homozygous or heterozygous for the trait in question?
The genotype of the individual is homozygous for the trait in question.
A scientist notices that a person has two recessive genes for a trait This describes the person's?
genotype for that trait.
What contains a dominant trait and a recessive trait?
Genotype
Is a genotype?

Is a gene a genotype that is not mixed?
No. A gene is a part of the DNA that identifies the outcome of a certain trait or part of a trait. A genotype is the actual definition of the gene for each individual.
What is responsible for an acquired trait?
Genotype
A plant with the genotype TT is called?
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
What is the pthenotype for each genotype?
Homozygous dominant genotype (AA): The phenotype will show the dominant trait. Heterozygous genotype (Aa): The phenotype will also show the dominant trait due to the presence of at least one dominant allele. Homozygous recessive genotype (aa): The phenotype will exhibit the recessive trait.
Which one is recessive Rr or RR?
The recessive trait is represented by the genotype rr, where both alleles are lowercase. The genotype RR represents the dominant trait.
