If you clasp your hand with your left thumb over your right, this is a dominant (more common) way of doing so. People who clasp their hands with their right thumb on top have the recessive genes. Left hand on top- Ll or LL right hand on top- ll

What is the different between dominant and recessive?
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
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 "
Is being left handed dominant or ressesive?
The answer is recessive. It is recessive because recessive is negative and left-handed is unordinary. Dominate people write with their right hand. Remember that!
Is colorblindness a dominant or recessive trait?
Color blindness is an inherited trait that can be passed on through reproduction but it has some peculiarities. It is recessive and not very prevalent in the gene pool. Because of this, color blindness does not appear very often in the population. In addition, it is a sex-linked gene on the X chromosome. Thus males only have one gene to express color vision. If it happens to be the recessive allele, then males are color blind. Females, on the other hand, must have both alleles recessive in order to be color blind.source: ciese.org/curriculum/genproj/activity35.html
What is the genotype of a carrier of recessive disorder?
A carrier is someone who does not have a disorder but carries the allele on to offspring.

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.

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 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.

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.
Can someone give you a List of dominant or recessive personality traits?
1. Shape of face (probably polygenic) Oval dominant, square recessive 2. Cleft in chin No cleft dominant, cleft recessive 3. Hair curl (probably polygenic) Assume incomplete dominance Curly: homozygous Wavy: heterozygous Straight: homozygous 4. Hairline Widow peak dominant, straight hairline recessive 5. Eyebrow size Broad dominant, slender recessive 6. Eyebrow shape Separated dominant, joined recessive 7. Eyelash length Long dominant, short recessive 8. Dimples Dimples dominant, no dimples recessive 9. Earlobes Free lobe dominant, attached recessive 10. Eye shape Almond dominant, round recessive 11.

Is having 6 fingers on one hand a dominant trait?
Yes having 6 fingers on your hand is a dominant trait. Most people who have this trait get the extra finger cut off after birth. There is a small group in the world where the people there have 6 fingers.
