For a person to express a recessive trait, such as having a big thumb, they must inherit two copies of the recessive allele, one from each parent. This means that both parents must either be carriers of the recessive allele (heterozygous) or express the trait themselves (homozygous recessive). If a person has a big thumb, it indicates that they possess the recessive alleles from both parents.
Having the left thumb cross over the right thumb is neither related to a recessive nor dominant gene. It is more of a behavior as to which thumb feels more natural on top when fingers are crossed.
The opposite of having a "green thumb" is having a "black thumb," which refers to a person who struggles to keep plants alive and may have difficulty with gardening or plant care.
The hitchhiker's thumb phenomenon, characterized by the ability to bend the thumb backward at an angle greater than 90 degrees, is often associated with a genetic trait influenced by alleles. Specifically, it is typically linked to the presence of a dominant allele, which allows for this increased flexibility. If an individual has at least one copy of the dominant allele, they are likely to exhibit hitchhiker's thumb, while those with two recessive alleles will not. Therefore, a person's alleles for this trait can be either dominant (hitchhiker's thumb) or recessive (normal thumb).
Hitchhiker's thumb is caused by a dominant allele. Individuals with at least one copy of the dominant allele will exhibit the thumb's characteristic flexibility, while those with two recessive alleles will have a straight thumb. This trait is a classic example of simple Mendelian inheritance.
Hitchhiker's thumb is a trait associated with a specific genetic variation, typically considered a recessive trait. If both parents carry one recessive allele for hitchhiker's thumb (heterozygous for the trait), they can pass this allele to their offspring. When the child inherits the recessive allele from both parents, they will express the trait, even though neither parent exhibits it. Thus, it's possible for two parents without the trait to have a child with hitchhiker's thumb if they are both carriers of the recessive gene.

In terms of genetics, the straight thumb trait is typically considered a dominant trait, while the curved thumb trait is considered recessive. This means that if a person inherits even one copy of the straight thumb gene, they are likely to have a straight thumb.
what thumb on top does not depend on the person being left or right handed but rather what gene a person have right thumb on top is recessive and left on top is dominate.

If a person's thumb literally turns green, it would be a symptom of decay. Green is not a good color for the human body.

Well the straight thumb is dominant while the hitch hikers thumb is recessive
The dominant trait is hitchhiker's thumb and the letter is H, and the recessive trait straight thumb is h

I'm guessing this is genetics question. If you cross your right thumb on to of the left, then you are homozygous recessive for this trait, i.e. both of your thumb crossing genes are of the recessive type. An uppercase C is used to designate a dominant gene and lowercase c for a recessive. Thus, both CC and Cc individuals still fold their left thumbs over the right, only cc individuals fold right over left.
