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.
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.
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.

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.
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.
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.
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.
basically, the hitchhiker's thumb is a physical characteristic that is inherited from your mother and/or father. when you were conceived, your mother gave you some of her genes, and your father gave you some of his. the hitchhiker's thumb is either a dominent or recessive trait. It if is dominant, you could have a heterozygous parent and still have a 100% chance of inheriting it. If the hitchhiker's thumb is recessive, you must have both of you parents homozygous for the gene to have a 100% chance of inheriting it. The alleles are either HH (homozygous dominant), Hh (heterozygous), or hh (homozygous recessive). H H << if the thumb is dominant trait, you have a 100% chance of getting it H HH HH << if the thumb is recessive trait, you have a 0% chance of getting it h Hh Hh
There are two phalanges in a human thumb: the proximal phalanx and the distal phalanx, making a total of two phalanges.
