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. =)

How is genetic engineering and Genocide related?
Genetic testing and genetic engineering are not related. Genetic testing is looking at the chromosomal constitution of an individual and determining if they have a genetic disorder. Genetic engineering on the other hand, is a much larger avenue and is almost a science in itself. This area of molecular biology deals with inserting foreign genes into organisms in order to increase yield or produce novel products. Genetic testing is useful to test if an unborn fetus has any genetic diseases. It is more of a diagnosis-based field. It can also be used to look at the chromosomes of an affected individual and their relatives to determine the cause and nature of a genetic disorder. Genetic engineering however, has applications like genetically modified foods, recombinant proteins and studying gene expression in a variety of different species.
How do captive breeding programs affect genetic diversity?
Captive breeding programs can affect genetic diversity in one of two ways. Within the program itself, genetic diversity is reduced, because captive breeding programs only have a limited number of animals to work with. On the other hand, animals from a captive breeding program that are re-introduced to the wild can increase genetic diversity, because they are bringing genes that may have been gone for a long time back into the gene pool.
Is maths necessary for genetic engineering?
yup.. maths is necessary ... bt only basics ..
What is the implication of technology of genetic engineering to modern man?
· Genetic engineering may be one of the greatest breakthroughs in recent history alongside the discovery of the atom and space flight, however, with the above eventualities and facts above in hand, governments have produced legislation to control what sort of experiments are done involving genetic engineering. In the UK there are strict laws prohibiting any experiments involving the cloning of humans. However, over the years here are some of the experimental 'breakthroughs' made possible by genetic engineering.
What evidence support the concept of the universal genetic code?
AnswerThe universality of the genetic code means that all living organisms are descended from one original organism, which is at least useful information. From a religious point of view, it could also be said that the creator god designed a successful genetic code and chose to use it universally. So, the genetic code does not actually prove or disprove evolution versus religion. But it proves the Theory of Evolution to be the best scientific explanation ofr life on earth.
Can inherited traits be changed by the position at birth of stars and planets?
There is no scientific evidence to support the idea that the position of stars and planets at the time of birth can change inherited traits. Inherited traits are determined by genetic information passed down from parents to offspring. The position of stars and planets, on the other hand, is not linked to genetic inheritance or the development of traits in offspring.
Differentiate between observed characteristics of plants and animals that are inherited and not inherited?
Observed characteristics of plants and animals that are inherited are traits that are passed down from one generation to the next through genetic information. These traits are typically consistent among related individuals. On the other hand, observed characteristics that are not inherited are those influenced by the environment, such as acquired traits or responses to external factors like diet or climate. These traits are not passed on through genetic material to offspring.
Why are acquired traits not directly related to evolution?
Acquired traits are not directly related to evolution because they are not passed down from one generation to the next through genetic inheritance. Evolution is driven by changes in the genetic makeup of a population over time, leading to the accumulation of advantageous traits through natural selection. Acquired traits, on the other hand, are characteristics that an individual develops during its lifetime and do not affect the genetic material that is passed on to offspring.
Does Selective breeding involve biotechnology?
Selective breeding does not necessarily involve biotechnology. It is a traditional method of breeding where organisms with desired traits are chosen to produce offspring with those traits. Biotechnology, on the other hand, involves using techniques like genetic engineering to manipulate the genetic material of organisms to create desired traits.
Which one genotype or phenotype exhibites traits by an organism?
Phenotype exhibits traits of an organism. It is the physical characteristics and traits that are directly observable, such as hair color or height. Genotype, on the other hand, refers to the genetic makeup of an organism that ultimately determines the phenotype.
Is Hand Clasping a dominant or recessive trait?
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
How can genetic drift and gene flow affect natural selection?
Genetic drift can reduce genetic variation within a population, making it harder for natural selection to act upon beneficial traits. Gene flow, on the other hand, can introduce new genetic variation into a population, potentially increasing the pool of traits for natural selection to act upon. Overall, both genetic drift and gene flow can influence the effectiveness of natural selection by altering the genetic composition of populations.
What are some examples of sex-linked traits and how do they differ from other types of genetic traits?
Sex-linked traits are genetic characteristics that are determined by genes located on the sex chromosomes, specifically the X and Y chromosomes. Examples of sex-linked traits include color blindness and hemophilia. These traits differ from other genetic traits because they are inherited differently based on the individual's sex. For example, males are more likely to inherit sex-linked traits from their mothers, as they only have one X chromosome. Females, on the other hand, have two X chromosomes, which can mask the expression of sex-linked traits if one X chromosome carries a normal gene.
What is genetic energy?
There is no scientific concept of "genetic energy." Genetics refers to the study of genes and heredity, which determine an organism's traits. Energy, on the other hand, is the capacity to do work. These are two separate and unrelated concepts in the field of science.
What is the difference between environmental factors and genetic factors?
Environmental factors refer to external influences on an organism, such as diet or pollution, that can impact its traits or behavior. Genetic factors, on the other hand, are inherited traits passed down from parents that can affect an organism's characteristics. Both environmental and genetic factors play a role in shaping an organism's phenotype.
What are the two major mechanism drives in evoloution according to Darwin?
The two major mechanisms of evolution according to Darwin are natural selection and genetic drift. Natural selection acts on heritable traits that affect an organism's ability to survive and reproduce in its environment, leading to the accumulation of beneficial traits over generations. Genetic drift, on the other hand, refers to random changes in the frequency of traits in a population due to chance events, which can lead to genetic variation over time.
What are the differences between SNP and allele in terms of genetic variations?
SNP (Single Nucleotide Polymorphism) is a specific type of genetic variation that involves a single nucleotide change in the DNA sequence. An allele, on the other hand, refers to different versions of a gene that can result in variations in traits. In summary, SNPs are a type of genetic variation at the nucleotide level, while alleles are variations of genes that can influence traits.
