recessive is when you have another allele that supress the recessive one, you have to thing how this could be done in a methabolic pathway, and you will see that exist many ways for an allele be dominant and the other recessive (you just can say dominant and recessive if you are talking at alleles ,this is genes at the same locus.
my mother language is no inglish maybe i have comit many gramatical errors but what i am saying is correc i am student of biotechnology.

What is the probability that a recessive trait will appear?
It depends on the genotype of the parents, but assuming there is an equal chance of being dominant homozygous, recessive homozygous or heterozgous and there are only two possible genes, there is a 1 in 4 chance that the recessive trait will appear.
What is a recessive allele?
Recessive allele is a trait that doesn't show in one's phenotype (observable trait) if there is a dominant allelle present. Only when you inherit a recessive allele from both parents (aa for example and not Aa) does the trait show in your phenotype.
What is the probability of a homozygous recessive offspring?
It depends. If it's a heterozygous cross, (Tt x Tt), there's a 25% chance. If it's a homozygous dominant cross (TT x TT), the chance is 0%. Neither parent has the alleles for a recessive trait, so none of their offspring can have the recessive trait. If it's a homozygous recessive cross (tt x tt), there's a 100% chance. The only alleles the parents can pass on are recessive.
If a dominant homozygous reproduced with a heterozygous could their offspring be recessive?
Let's see what combinations can be formed.HH, HH, Hh, Hh.So, yes their offspring can contain the recessive allele.(THe offspring can be a carrier of the recessive allele.)However, since it is impossible for the offspring to be homozygous recessive,the recessive trait/gene will not show in the offspring's phenotype.Hope that helps!
Is it possible for 2 homozygous recessive individuals to have a homozygous dominant child?
No, homozygous recessive indivuals MUST have two of the reccessive gene (bb), the possible combinations are bb,bb,bb,bb thus only a recessive trait is possible
A trait that is hidden?
The trait that is hidden is recessive trait.
What is a trait called?
recessive trait
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
What is the name given to the weaker trait that can be covered up by the dominant trai?
The weaker trait that can be covered up by the dominant trait is called a recessive trait. It is only expressed when an individual has two copies of the recessive allele.
What gene won't display its trait in the prescience of a dominate trait?
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.
In mendels experiment a trait that always disappeared in the f1 generation but reappeared in the f2 generation was called the?
recessive trait
What is an observable trait of an organism that can mask a recessive trait?
An observable trait of an organism that can mask a recessive trait is called a dominant trait. Dominant traits are expressed in the offspring even if they only have one copy of the dominant allele, hiding the recessive trait's expression.
What did Mendel call the observed trait and the trait that seemed to disappear?
Mendel called the observed trait the dominant trait and the trait that seemed to disappear the recessive trait.
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A recessive trait is a characteristic of an organism that can be masked by the dominant form of a trait. It is only expressed when an individual inherits two copies of the recessive allele. Examples include blue eye color being masked by brown eye color.
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.
The form of a combination of two traits that may be hidden is called a trait?
The form of a combination of two traits that may be hidden is called a recessive trait. This means that the trait is not expressed unless an individual has two copies of the recessive allele.
