- lack of clotting factor 11 or Hemophilia is inherited Pattern of Inheritance - The genes associated with these conditions are located on the X chromosome‚ which is one of the two sex chromosomes. In males (who have only one X chromosome)‚ one altered copy of the gene in each cell causes the condition. In females (who have two X chromosomes)‚ a mutation would have to occur in both copies of the gene to cause the disorder. What is the role of genetic testing ? - Genetic testing for Hemophilia

23 chromosomes from the mother and 23 from father; each cell in the human body (Except gametes) contains 46 chromosomes arranged into 23 x and 23 y‚ which determine the sex of a person. On the 23rd pair of chromosomes‚ Males have an XY and females have an XX. Sickle cell anaemia is an autosomal recessive disease‚ which is inherited when both parents carry the

Africa. Spencer Wells quest to find the genetic marker to link ancestors over 60‚000 years ago is done by taking blood samples from hundreds of men on the migration route. Women were not sampled because the X chromosome evolves‚ thus only the Y chromosome could be used. I was astonished by the process used to retrieve DNA from blood that Wells shows the viewers. In the hundreds of samples of blood taken‚ Spencer Wells scouts for a certain feature in a DNA strand and finds

Bonnevie-Ullrich syndrome‚ Gonadal dysgenesis‚ and Monosomy X. The syndrome is a non-inherited chromosomal condition that only occurs in females. It’s cause when there is a complete or partial absence of the second x chromosome. A person with TS has monosomy X‚ which means that it only has one pair of X chromosome on all or some of it’s cells. When it’s only in some cells is called mosaicism. If a women has this syndrome and it’s a prime mover x-chromosome mosaicism. she is known for having a mosaic turner

but also his future. In natural child conception‚ the mother provides the the two X chromosomes and the father provides the X and Y chromosomes. The balance of genetic make up is determined by the father since he is the only one that has the diversity of genes. With all this‚ the genetic combinations are completely random‚ allowing much room for fault. With science controlling the joining of such chromosomes‚ many of the fatal or physically impairing infant diseases will disappear. Scientist’

and Catharanthus roseus (L.) Don. (periwinkle) were studied using iron-acetocarmine squash technique. The chromosome number of C. roseus is 2n=16 while both M. oleifera and E. pulcherrima have 2n=28. Although late disjunction and presence of laggards were noted at Metaphase I‚ Anaphase I and II‚ Telophase I and II were 100% normal. These would indicate that lagging chromosomes were able to catch up‚ reached the opposite poles‚ and were included in daughter nuclei. Highly normal meiosis
