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
A trait that is hidden?
The trait that is hidden is recessive trait.
What causes a branch in a cladogram?
A new trait a derived trait
What is the phenotype of AAA?
It's impossible to say without more information. The genotype AA is called homozygous dominant for the trait that is encoded by the letter A (or a). Whatever trait A stands for on your homework, the answer is the dominant one is expressed in the phenotype.
Which is a non medelian trait?
a trait controlled by many genes
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.
What are the possible genotypes of a person with a straight thumb?
Ugh I'm stuck on the same question! And I have no clue :(
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.
To represent a trait to be crossed do you always use capital letter for dominant trait?
Yes
Is the hitch hiker's thumb the dominate trait?
the hitchhiker's thumb is the recessive trait. normal thumbs are dominant. i learned this in science class and i am doing a family pedigree on the hitchhiker's thumb.
Does the big letter or little letter represent a dominant trait?
In genetics, dominant traits are typically represented by a capital letter, while recessive traits are represented by a lowercase letter. For example, "B" might represent brown eyes as a dominant trait, while "b" represents blue eyes as a recessive trait.
When a straight thumbed homozygous person has offspring with a hitchhiker's thumbed homozygous person the offspring will have which trait?
Straight thumbs, hitch hiker's thumb is recessive...so the F1 generation in this example would be heterozygous and have the dominant (straight thumbed) phenotype.
Is hitchhiker's thumb a X linked trait?
No, hitchhiker's thumb is not an X-linked trait; it is a result of a genetic variation that is considered to be an autosomal trait. This means it can be inherited from either parent, regardless of the sex of the offspring. The trait is associated with the flexibility of the thumb joint, and its inheritance pattern follows a simple Mendelian trait pattern rather than being linked to the sex chromosomes.
What type of letter do you use to represent a dominant trait?
Capital letter such as R for dominant and r for recessive trait
What do the letters represent in punnett square crosses?
The letters represent the alleles, or variations, of a given trait. So for example T might represent tall and t represents short. The capital letter always corresponds to the dominant trait and the lowercase letter corresponds to the recessive trait.
Having to bent thumb is a recessive trait in humans the trait is controlled by a single gene how many recessive alleles must a person have to have a bent thumb?
2
What is the letter that represents a recessive allele?
The letter that represents a recessive allele is typically a lowercase letter, such as "a" or "b." In genetics, uppercase letters are commonly used to represent dominant alleles and lowercase letters represent recessive alleles.
