What is common autosomal trisomy
It’s when there is one extra chromosome and monosomy in which there is one less, than the normal 46. They rarely cause specific eye diseases but affected individuals present ocular manifestations. Examples: Down’s syndrome. ChaCha on! [ Source: http://www.chacha.com/question/what-is-common-autosomal-trisomy ]

- 3 (4??) bio 101 questions.?
- Q: Hello everyone, these are three multiple choice questions from bio 101 class. These three are ones I couldn’t answer at all or confused. Please take your time and help me with it. You don’t have to answer all but do ones you know for sure. Thank you very much in advance!!!1.Hutchinson-Gilford progeria syndrome (the aging disease)a.is controlled by a simple recessive gene.b.is a sex-linked disease more common in males.c.occurs only in those individuals in which a mutation arises and is not found in other members of the family.d.is the result of the failure of chromosomes to separate so that an individual receives three instead of two chromosomes.e.none of these2.Four of the five conditions below are related by their abnormal numbers of chromosomes. Select the exception.a.monosomyd.complete chromosome setb.aneuploidye.trisomyc.nondisjunction3.Four of the five organisms listed below are widely used in genetic research. Select the exception.a.peasd.dogfish sharkb.fruit fliese.E. colic.bread mold4?? And there is this question with pedigree diagram shows the inheritance of an autosomal dominant disorder. Question is what is the genotype of “d”? and choices are…a) aab)Aac)AAd)either aa or Aae)either Aa or AAsince I can’t post diagram here, I will do my best to describe it. On very top, there is two light colored circle on left and rectangle on right. Then line connects them together then moves down to next level. On next level, that line connects to black colored circle, then line from that cirlcle connects to light colored rectangle. Then line from those two moves down to next level. On next level, it seperates to 5 different column (BUT I will only describe one which is for the question). That line connects to black circle then the line from circle connects to light rectangle. Then another line from that moves down to next level. Here, line seperates to 5 different shapes. The “D” which question is asking I on far right with black colored circle. It would sound much easier if you draw it out actually.
- A: 1. C. “Hutchinson-Gilford progeria syndrome is considered an autosomal dominant condition, which means one copy of the altered gene in each cell is sufficient to cause the disorder. The condition results from new mutations in the LMNA gene, and almost always occurs in people with no history of the disorder in their family.” (http://ghr.nlm.nih.gov/condition=hutchinsongilfordprogeriasyndrome)2. I believe it’s D.3. D. sharks are not often used in genetics experiments.4. sorry, from your description, I have no idea what’s going on!
