What else can I help you with?
What is Only expressed when the other allele is absent?
The term you're looking for is "recessive allele." A recessive allele is only expressed in an organism's phenotype when two copies are present, meaning the corresponding dominant allele is absent. In other words, for a trait associated with a recessive allele to be visible, the individual must inherit the recessive allele from both parents. If at least one dominant allele is present, it will mask the expression of the recessive allele.
When a alleles creates a visible trait you call it what?
When an allele creates a visible trait, it is called a dominant allele. Dominant alleles mask the expression of recessive alleles when present in a heterozygous individual.
What trait is expressed when two different genes for the same trait are present is called?
It depends which one is the dominant gene, and which is recessive. Dominant always over rules recessive. I probably spelled recessive wrong so yeah... :P
What does recessive mean as it relates to genes?
A recessive gene is one that is only expressed if an individual has two copies of that gene. This means that the trait associated with the recessive gene is not visible unless an individual inherits two copies, one from each parent. If an individual inherits only one copy of a recessive gene, the dominant gene will be expressed instead.
In which generation were recessive traits visible Mendel's experiments?
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
What genotypic condition must be present for a recessive trait to be visible?
if the ratio had more recessive traits, like if you made a punnit square and you saw that there were more of the recessive traits (BB bb bb bb) then you know that the most common trait is the recessive one "bb" (considered as homozygous recessive ( i think))
Traits and their meanings of scientists?
traits are the phenotypic and genotypic characters which may or may not be visible in individual but present as a particular genetic code in each organism.
What is trait called that appear only when both alleles are present?
A trait that appears only when both alleles are present is called a recessive trait. In this case, the trait is masked when the dominant allele is present, but becomes visible when two copies of the recessive allele are inherited.
What is Only expressed when the other allele is absent?

During interphase the chromosomes are not visible but the nuclear material is present in a granular or network condition?
chromatin
Is recessive traits visible?
Recessive traits are only visible if an individual inherits two copies of the recessive allele, one from each parent. If an individual has only one copy of the recessive allele, the dominant allele will be expressed, masking the recessive trait.
Is Recessive alleles the traits visible in the F1 generation of true-breeding organisms?
Only if the generations before were homozygous recessive as well. When doing the punnett square and you see there is a chance of having a heterozygous trait then that specie is not a purebred. The organism's offsprings must have the same physical traits.
In which generation were recessive traits visible Mendel's experiments?
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
What did Gregor Mandel discover about recessive traits?
Gregor Mendel discovered that recessive traits do not manifest in an organism's phenotype unless two copies of the recessive allele are present. In his pea plant experiments, he observed that when a dominant allele is paired with a recessive allele, the dominant trait dominates the phenotype. Only when both alleles are recessive does the recessive trait become visible in the offspring. This foundational principle of inheritance laid the groundwork for modern genetics.
