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

Hand clasping is a polygenic trait, meaning it is influenced by multiple genes and environmental factors rather than being strictly dominant or 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.
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 "
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.
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.
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.
