One may also ask, what is an example of a dominant genetic disorder?ДЄ single abnormal gene on one of the first 22 nonsex (autosomal) chromosomes from either parent can cause an autosomal disorder. Recessive- organism that has a recessive trait. Dominant allele- produces the same phenotype either paired or identical or different. Dominant inheritance means an abnormal gene from one parent can cause disease. Examples of autosomal dominant disorders include Marfan syndrome and neurofibromatosis type 1.Д¬hromosomes are passed from parents to offspring via sperm and eggs. The specific kind of chromosome that contains a gene determines how that gene is inherited. Simple dominant traits need only 1 allele in order to express phenotype вЂ“ RR or Rr Examples: HuntingtonвЂ™s disease Cleft chin, widowвЂ™s peakДЎ homozygous dominant 2 heterozygous 1 homozygous recessive R r RR Rr rr R rДЄutosomes Karyotype: chart that shows all of one individualвЂ™s chromosomes arranged in pairs (one from mom, one from dad) Autosomes: non-sex chromosomes (chromsomes #1-22) Sex chromosomes: Chromosomes that determine an individualвЂ™s gender (chromosome #23 вЂ“ X and Y) Sex chromosomesД¤ Autosomal Dominant Disorder: HuntingtonвЂ™s Men have one X chromosome, from their mother, and one Y chromosome, from their father.Presentation on theme: 'Simple Dominant Traits'- Presentation transcript: De La Salle Araneta University Probability of Trait in a Population (Survey on Dominant-and- Recessive Trait) Abstract: The survey result shows a variation of this research. Huntington's disease is an inherited disease that causes the progressive breakdown of nerve cells in the brain.
