About

Hitchhikers thumb hasnt been studied extensively, and there is little to no data on its prevalence in the united states or worldwide. Hitchhikers thumb is otherwise known as distal hyperextensibility of the thumb. This is because of the genetic traits that make a person bend his thumb backward while stretching. The gene that controls the extendibility of the thumb is known as the bendy thumb gene. The bendy thumb gene comprises of multiple alleles in the chromosomes. One allele from the bendy thumb gene can produce a straight thumb and another allele may produce a hitchhikers thumb. It all depends on what allele people receive from their parents. Some people have hitchhikers thumbs, which bend backwards with a large angle between the two segments (phalanges). The myth is that there are just two kinds of thumbs, straight thumbs (s) and hitchhikers thumbs (h), and the trait is controlled by a single gene with two alleles, with the allele for s being dominant.   the only outcome above that will display the hitchhikers thumb is the aa combination of alleles. In my particular situation, my father displays the hitchhikers thumb, so his genetic makeup is aa. I display the hitchhikers thumb, so mine must also be aa. Widows peak and hitchhikers thumb are dominant traits controlled by a single autosomal gene. Sex-linked traits traits controlled by genes on the sex chromosomes are called sex-linked traits , or x-linked traits in the case of the x chromosome. A characteristic of an organism that is determined by specific proteins coded in the dna (ex. The passage of genetic instructions from one generation to the next generation. The monomer of dna made of 3 parts - deoxyribose sugar, phosphate.). On the chromosome map a gene(s) may cause a genetic disorder. Scientists use pedigrees as a tool to identify a gene associated with a genetic disorder, and to map that gene to a specific location on the chromosomes.
