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.

Is hitch-hikers thumb dominant or recessive?

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.

Is a Straight thumb dominant or recessive?

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.


How do you xxplain how the hitchhicker's thumb trait is determined using the following words allele domnate recessive homozygous heterozygous?

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


Having a big thumb is a recessive trait in a human body and how many recessive ally I was a person have to have a bit mom?

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.
