Why do dominant alleles genes or traits always show up?
Dominant alleles express their traits even when only one copy is present, masking the effect of any recessive alleles. This occurs because dominant alleles typically produce functional proteins or traits that are observable, while recessive alleles may not produce a functional product or may only do so when two copies are present. As a result, dominant traits are more likely to show up in the phenotype of an organism.
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.
What are inactive alleles?
Inactive alleles are versions of a gene that do not produce a functional protein or have reduced activity due to mutations. These alleles may not contribute to the individual's phenotype or may have a diminished effect compared to active alleles. Inactive alleles can result in genetic disorders or variations in traits.
What are the characteristic of multiple alleles?
1) Multiple alleles are always on the same location (locus) on the alleles.2)they always effect the same character.3)They always occupy the same gene locus on chromosome.4)no crossing over is known to occur on chromosome.5)a single multiple allelic series affects only one trait _eye color etc
What combinations of alleles could produce a trait controlled by a recessive alleles?
recessive + recessive or tt
What are alleles for a particular trait that are always expressed are said to be?
Dominant alleles. Dominant alleles will always be expressed in the phenotype, even if only one copy is present in the genotype.
What Interact to produce a trait in which neither dominant gene can produce its effect in the presence of the other?
The interaction that leads to a trait where neither dominant gene can express its effect in the presence of the other is known as "codominance." In codominance, both alleles contribute to the phenotype, resulting in a distinct expression that is a combination of both traits. For example, in certain flowers, one allele may produce red petals and another may produce white petals, resulting in flowers with both red and white patches when both alleles are present. This differs from complete dominance, where one allele completely masks the effect of the other.
In what alleles can be observed in the phenotype?
you mean phenotype, and its dominant alleles
Do all heterozygous pairs of alleles produce an intermediate?
No
What does alleles always come in?
Alleles are generally inherited in pairs, except for alleles on the X and Y sex chromosomes in males.
How do multiple alleles control the trait?
In the case of multiple alleles, one trait is governed by more than two alleles. One example is the human ABO blood group. There are three alleles, A, B, and O. A person can, however, only inherit two of the three alleles.
Is it possible for 2 alleles to produce 4 phenotypes?
yes
