What does a capital letter in phenotype stand for?
A capital letter in a phenotype typically stands for the dominant allele or trait. This means that if an organism has at least one copy of the dominant allele, the corresponding trait will be expressed.
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.
What does it mean that an organism is homozygous dominant for a trait?
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
What happens if an organism has two factors for a domintnat trait?
If an organism has two factors (alleles) for a dominant trait, the dominant allele will be expressed in the phenotype. This is because dominant traits mask the effect of recessive alleles, so the presence of two dominant alleles will result in the dominant trait being displayed.
The stronger of the two traits which show up in an organism is called a?
dominant trait. It is more likely to be expressed in the phenotype of an organism when it is inherited with a recessive trait.
If two genes in a gene pair are for the same trait what will that trait be?
The question should be "If two alleles for a gene are the same, what phenotype will the organism have?" Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.
Organisms that are homozygous dominant and those that are for a trait controlled by simple dominance have the same phenotype?
Because the dominant gene always appears in the phenotype, whether or not it is "pure" (homozygous) or "mixed" (heterozygous). The recessive gene does what it says: it is recessive to the dominant gene. So, if it comes between the two, the dominant always appears. Of course, this only happens in your average Dominant-Recessive traits.
What are an individuals expressed traits called?
genotype
What is phenotype of Rr?
It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. It is Dominant. R is the dominant and r is the recessive. The dominate trait shadows the recessive trait. Is dominant. dominant can be RR or Rr. but when its recessive its rr.
What are alleles that have an effect on an organisms phenotype?
Alleles that have an effect on an organism's phenotype are called dominant alleles. Dominant alleles mask the effects of recessive alleles in heterozygous individuals, resulting in the dominant allele's phenotype being expressed.
Organisms that has two different alleles for a trait?
An organism with two different alleles for a trait is said to be heterozygous for that trait. This means that it has one dominant allele and one recessive allele. The dominant allele will usually determine the organism's phenotype for that trait.
What word is used to describe an observable trait or characteristics?
The word used to describe an observable trait or characteristic is "phenotype." Phenotype refers to the physical characteristics or traits of an organism that result from the interaction of its genetic makeup (genotype) with the environment.
