Answer:
Non-disjunction
Explanation:
non-disjunction is occuring during anaphase I of meiosis I, this means that at least one pair of homologous chromosomes did not separate. The end result is two cells that have an extra copy of one chromosome and two cells that are missing that chromosome
fun facts:
(Nondisjunction occurs when chromosomes fail to segregate during meiosis; when this happens, gametes with an abnormal number of chromosomes are produced. The clinical significance is high: nondisjunction is the leading cause of pregnancy loss and birth defects)
The lipid bilayer<span> has been firmly established as the universal basis for cell-</span>membrane<span> structure. It is easily seen by </span>electron<span> microscopy, although specialized techniques, such as x-ray diffraction and </span>freeze-fracture electron microscopy<span>, are needed to reveal the details of its organization. The bilayer structure is attributable to the special properties of the </span>lipid<span> molecules, which cause them to assemble spontaneously into bilayers even under simple artificial conditions</span>
Inner planets have a shorter revolution time because they have a far shorter distance to travel.
Answer:
1/8
Explanation:
In genetics as a whole there are few topics that impinge on human affairs quite so directly as this one. Foremost is the fact that a large proportion of genetically determined ill health in humans is caused by abnormal chromosome numbers. Additionally, manipulation of chromosome number is routinely used by breeders to improve agriculturally important species.
