    group. The telomeres are indicated by the circles at ends of linkage groups. Breakpoints of chromosomal rearrangements distinguishing the taxa are indicated by the double squiggles. The existence of homologous gene between the populations shows that Poaceace is relatively conservative. However, certain lineages in this family appear to be rapidly evolving. The genome of wheat and rye are different by 13 chromosomal rearrangements after only 6 million years of divergence (Devos). This rate is…

  • Essay On Turner Syndrome

    Turner syndrome, also known as TS and gonadal dysgenesis, is a chromosomal deficiency affecting over two million women that occur when two of the X chromosomes in a female’s DNA are either incomplete or missing entirely.

  • Essay On Preimplantation Genetic Testing

    Preimplantation genetic testing is a genetic technique in which cells are removed from embryos to examine chromosomal abnormalities in vitro fertilization before a woman gives birth (King). Embryos made through in vitro fertilization would face genetic modification to avoid passing the defects onto future generations. After modification, only embryos free of abnormalities would be placed into the mother’s womb. This technique is targeted for parents who have a high risk of passing a fatal…

  • Characteristics Of Down Syndrome

    Background: What is Down Syndrome? Down Syndrome is a chromosomal disorder caused by an error in cell division that results in an extra twenty-first chromosome, that causes birth defects of developmental and intellectual delays. The human body is composed of trillions of cells and within the nucleus of each cell are structures called chromosomes (Parks, 2009). About eight million babies are diagnosed with Down Syndrome in the United States with approximately twenty thousand in Western Europe…
