Hitchhikers thumb is a recessive trait while a straight thumb is dominant.
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.

Clubbed Thumb was created in 1996.
Hitchhikers thumb is a recessive trait while a straight thumb is dominant.
Well the straight thumb is dominant while the hitch hikers thumb is recessive
ressesive

Hair curl (probably polygenic) Assume incomplete dominance Curly: homozygous Wavy: heterozygous Straight: homozygous 4. Hairline Widow peak dominant, straight hairline recessive 5. Eyebrow size Broad dominant, slender recessive 6. Eyebrow shape Separated dominant, joined recessive 7. Eyelash length Long dominant, short recessive 8. Dimples Dimples dominant, no dimples recessive 9. Earlobes Free lobe dominant, attached recessive 10. Eye shape Almond dominant, round recessive 11. Freckles Freckles dominant, no freckles recessive 12. Tongue rolling Roller dominant, nonroller recessive 13. Tongue folding Inability dominant, ability recessive 14. Finger mid-digital hair Hair dominant, no hair recessive 15. Hitch-hiker's thumb Straight thumb dominant, hitch-hiker thumb recessive 16. Bent little finger Bent dominant, straight recessive 17. Interlaced fingers Left thumb over right dominant, right over left recessive 18. Hair on back of hand Hair dominant, no hair recessive 19. Tendons of Palmar Muscle Two tendons dominant, three tendons recessive
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
The dominant trait is hitchhiker's thumb and the letter is H, and the recessive trait straight thumb is h
Yes, hitchhiker's thumb is a dominant trait. This means that if one of the parents has a hitchhiker's thumb, there is a high likelihood of their offspring inheriting this 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
