What is the different between dominant and recessive?
Dominant traits are expressed when an individual carries at least one copy of the dominant allele, while recessive traits are expressed only when an individual carries two copies of the recessive allele. Dominant alleles mask the expression of recessive alleles in heterozygous individuals.
In your own words what does the term recessive trait mean?
A recessive trait is the opposite of a dominant trait. A dominant trait is the trait that overpowers another trait- represented by a capital letter. The recessive trait is the trait that is weaker, and being overpowered- represented by a lowercase letter. For example, if one person had a recessive trait for detached earlobes, it would be represented as " aa ",. If someone had a dominant trait for attached earlobes (meaning they had free earlobes), it would be represented as "AA"or " Aa "
What is the diminent and recessive?
In genetics, a dominant trait refers to a gene that will be expressed if present, even if only one copy is inherited. A recessive trait, on the other hand, requires two copies of the gene to be expressed. Dominant traits mask recessive traits when both are present in an organism's genetic makeup.
What is the difference between a Pure tall plant and hybrid tall plant?
A pure tall plant refers to one that has been consistently bred with other tall plants of the same variety to maintain its tall characteristics. A hybrid tall plant, on the other hand, results from cross-breeding two different varieties of plants to create a new plant with varying characteristics, such as height.
Is being left handed dominant or ressesive?
Left-handedness is considered to be less common than right-handedness, but it is not necessarily dominated by right-handedness. There is no clear answer as to whether left-handedness is dominant or recessive, as it is influenced by a combination of genetic, environmental, and cultural factors.
Information on hand clasping genetic traits?
Well there are some genetic traits controlled by a couple of alleles (hand calsping, tongue rolling, ear lobe attachment, etc.). and there are other controlled by many alleles (as hair color, eye color, skin color, height, etc.). Hand clasping is one trait that, so far as I know, some people believe it is controlled by just one pair of allels other people think it is controlled by many of them. I prefer to believe hand clasping just has 2 alleles. Considering this, we can say that one of this 2 alleles is Dominant and another recessive, as usually, however there are some cases when both alleles are dominant. -What do I mean by dominant and recessive? Well, this means that if both are in the same locus for that genetic trait (or gene, it is the same) the dominant will be the one that will expressed in the person carrying these alleles for this gene (or genetic trait, it is the same =P). So in the cae of hand clasping, if you join the fingers of your hand (I do not how to explin it exactly), you should see wheter your right or your left thumb is up. If your left thumb is above your right that is the dominant trait expressing. And if your right thumb is above , well you have the reccesive allele expressing. I hope I had contribute. =) Giorgio.

Is hitch-hikers thumb dominant or recessive?
The ability to hitchhike (extend the thumb back to a right angle to the hand) is typically considered a dominant trait. This means that if one parent has the ability to hitchhike and the other does not, their offspring are likely to inherit the dominant trait and be able to hitchhike.
Why do recessive trail are more common in some cases?
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more of it in the gene pool. Also, since dominant traits are expressed over recessive traits, natural selection has more of an effect on them.
What is the different between dominant and recessive?
Dominant traits are expressed when an individual carries at least one copy of the dominant allele, while recessive traits are expressed only when an individual carries two copies of the recessive allele. Dominant alleles mask the expression of recessive alleles in heterozygous individuals.
What is the difference between dominant and recessive alleles for specific traits?
Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
Why do x linked conditions appear more frequently in males than females?
Because males have an X and Y chromosome. If the trait is X-linked (recessive), there is nothing to mask the expression. On the other hand if a woman has an x-linked recessive allele and a dominant one, the dominant trait is the one that will be expressed.
In your own words what does the term recessive trait mean?
A recessive trait is the opposite of a dominant trait. A dominant trait is the trait that overpowers another trait- represented by a capital letter.

What is the difference between a dominant and recessive allele?
Dominant is an allele that can be expressed in a heterozygous individual (ie. Bb) or homozygous dominant (ie. BB). Recessive on other hand are traits that will only be expressed in a homozygous recessive (ie. bb) condition. Under normal circumstances, dominant alleles are the ones expressed in the phenotype, while the recessive allele is not. For example (an extremely simplified example) an heterozygous individual for eye color. (genotype Bb), has one dominant allele, 'B', and one recessive allele, 'b'. Given that B is for brown eyes, and b is for blue eyes, that individual's phenotype would be expressed as brown eyes (and be recessive for blue eyes). Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
How are dominant and recessive traits represented?
Autosomal recessive alleles ( both males and females) and X-linked alleles in females always express themselves in homozygous condition. On other hand, X -chromosome linked recessive allele express singly in males.
How is probability related to genetics?
Probability and genetics go hand in hand. Mendel in his charts showed the probability of dominant and recessive genes being passed on to offspring. The desired trait could be cultivated knowing the probability of inheritance.
How does a dominant form of an allele affect the expressions of a recessive form of an allele?
If you have a heterozygous (one dominant and one recessive) individual, it will only express the dominant allele in complete dominance; if it's codominance then some sort of "combined property" resulting from both the dominant and recessive allele would be expressed. On the other hand if you have a homozygous (both dominant or both recessive) you needn't bother.
