No, the hitchhiker's thumb refers to a genetic trait that allows the thumb to bend backward at an angle greater than 90 degrees. It is not a gesture but a physical characteristic.
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.
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.
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).

Well the straight thumb is dominant while the hitch hikers thumb is recessive

They could have hitchhikers thumb, widows peaks, attached earlobes, and the ability to roll the tongue.

No. strickly speaking hitchhikers thumb is autosomal recessive. that means each parent has two copies of the gene if they are true "hitchhikers". That means the only possible outcome is that all offspring will also have two copies. Of course if one of the parents is just hyperextendible and does not have the genes that's different. The child could also just not be very extendible but have the genes. But genetically there is no other options.
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.
