∙ 14y agoA recessive trait needs two copies of an allele to be expressed. Dominant traits are expressed when either two copies of an allele are expressed OR in the heterozygote.
A: Dominant (will be expressed as AA or Aa)
a: recessive (will be expressed only as aa)

∙ 14y agoa recessive allele must be present two times to be expressed, but in traits with multiple alleles there may be different degrees of recessiveness
ex: blue eyes, blonde hair, O blood type,...

∙ 6y agoA dominant allele or a recessive allele. If both parent alleles code for a dominant trait, the offspring will be homozygous dominant for that trait, and will exhibit the dominant phenotype; and if both parent alleles code for a recessive trait, the offspring will be homozygous recessive and exhibit the recessive phenotype.

Comapre and contrast dominant and recessive traits?
Dominant traits only require one allele to be present in order for the trait to be expressed, while recessive traits must have both alleles present in order for the trait to be expressed.
What is a trait that is not expressed when an organism receives genes for 2 different forms of a trait?
A trait that is not expressed when another is present is referred to as a recessive trait.
What in term of applied to the trait that is expressed irregardless of the second allele?
The term applied to the trait that is expressed in regardless of the second allele is dominant. In contrast, the term recessive refers to a trait that is expressed when the second allele is identical.
What did mendel call the trait that always showed up?
Mendel called the trait that was always expressed the dominant trait.
The difference between a dominate and a recessive trait is?
A trait is dominant if it continues to be expressed in the heterozygous as well as the homozygous state. Recessivetraits are only expressed in the homozygous state.
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
Comapre and contrast dominant and recessive traits?
Dominant traits only require one allele to be present in order for the trait to be expressed, while recessive traits must have both alleles present in order for the trait to be expressed.
What is a trait that is not expressed when an organism receives genes for 2 different forms of a trait?
A trait that is not expressed when another is present is referred to as a recessive trait.
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What is the expression of a trait and is determined by the combination of alleles?
The expression of a specific trait in an individual (such as hair color) is determined by two factors,one from each parent. These factors are represented with an uppercase letter for a dominantfactor and a lowercase letter for a recessive factor. The combination of these factors determineshow that trait will be expressed in an individual.
What do you call the physical trait that is displayed?
It is called an expressed trait.
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What in term of applied to the trait that is expressed irregardless of the second allele?
The term applied to the trait that is expressed in regardless of the second allele is dominant. In contrast, the term recessive refers to a trait that is expressed when the second allele is identical.
What trait is expressed when two different genes for the same trait are present?
dominant
When do you see a dominate trait?
When the allele that codes for the dominant trait is expressed in the genome.
A trait that appears or is expressed in the f1 generation is what?
the dominant trait
