In genetics dominance refers to the relationship between the alleles of a single gene. If as an example we assume that only two alleles exist, these being A and B and we also assume that genes only have two alleles then there are only three possible combinations:- AA, BB and AB. If we look the individuals with the AA gene and find they are different from the individual with the BB gene then it is impossible to say which allele is dominant. This can be found by looking at the AB individuals, if they are the same as the AA individuals then the A allele is dominant, if they resemble the BB individual then the B allele is dominant.
What else can I help you with?
Mendel referred to the characteristic that was expressed in the hybrid F1 or first filial generation as?
Mendel referred to the characteristic expressed in the hybrid F1 generation as the dominant trait. This trait masks the expression of the recessive allele in the heterozygous individual.
What gene is defined as a gene that controls the appearance of a certain trait?
The gene defined as controlling the appearance of a specific trait is referred to as the "gene for that trait" or "trait-specific gene." These genes can influence physical characteristics like eye color, height, or leaf shape.
A dominant phenotype will only be expressed if the individual is homozygous dominant for that trait?
Well actually not necessarily. An individual can be homozygous or heterozygous dominant for a trait. As long as they have that dominant allele in that specific genetic trait, they will automatically express the dominant phenotype. If a person is homozygous dominant, it just means that they will pass on both dominant traits to the offspring. If a person is heterozygous dominant , it means that they will pass on both a dominant and recessive trait to their offspring.Hope that helps ! =D
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
Two alleles for a certain trait are passed to an individual. what terms refers to the trait that will show up in the individual?
The allele that is expressed in an individual is referred to as the dominant allele. This allele masks the effect of the recessive allele when present.
An organism which the two genes for a given trait different?
An organism that has two different alleles for a given trait is referred to as heterozygous for that trait. For example, if one allele codes for a dominant trait and the other for a recessive trait, the dominant trait will typically be expressed in the organism's phenotype. This genetic variation can contribute to diversity within a population and may influence the organism's adaptability to its environment.
A living thing that shows a dominant trait may be homozygous dominant or homozygous recessive for the trait true or false?
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
What is a trait that masks a trait called?
A trait that masks another trait is called a dominant trait. This means that when an organism carries both dominant and recessive alleles for a particular gene, only the dominant trait will be expressed in the phenotype.
The form of a trait that appears to mask another form the same trait is called what?
The form of a trait that appears to mask another form of the same trait is called the dominant trait. Dominant traits will be expressed over recessive traits in a heterozygous individual.
A trait that appears or is expressed in the f1 generation is what?
A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
What is an observable trait of an organism that can mask a recessive trait?
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
