Question 6
The “What is a traits?” video (part of the genetics primer) talks about the trait of the hitchhikers thumb. If you have a hitchhikers thumb which genotype or genotypes could you have?
Select one or more:
a. hh
b. Hh
c. HH
Inherited charicterstics which is passed by your parents is called traits,A gene may have several forms eachform is called an allele, and this allele can be dominent or recessive,people with curved thumb have dominent traits.Hitchhiker's thumb because of the genetic traits that make a person bend his thumb backward while stretching.
There are a number of genes that determine the size, shape, and color of a person, gene that controls the extendibility of the thumb is known as the "Bendy thumb gene."One allele from the bendy thumb gene can produce a straight thumb and another allele may produce a hitchhiker's thumb.
Alleles are usually represented by capital or lower case letters. Dominant alleles are expressed by capital letters, whereas recessive alleles are expressed by lower case letters. A person who inherited the dominant hitch-hiker's thumb alleles from both parents could be called the genotype HH. A person who does not have a hitch-hiker's thumb could be called the genotype hh.
