By left I guess that you mean the western side of the Pacific Basin. There is no longer a spreading ridge on the western side of the Pacific Basin--so the floor is no longer spreading. The seafloor and the paleomagnetic stripes on the seafloor of the Western Pacific were actually created many millions of years ago. In fact, the western side of the Pacific Basin is being subducted--so, the western ocean floor is actually disappearing beneath Japan, New Zealand, etc.
<span>In the southeastern part of the Pacific, there is still a spreading ridge, the East Pacific Rise, off of Central and South America. And there are little remnants of spreading ridges just off the the Northwest coast of North America </span>
<span>The Atlantic Basin, on the other hand, which has a spreading ridge right down its middle, and has only insignificant subduction along its margin (beneath Caribbean plate), is still getting wider. </span>
Answer:
Sex linked inheritance may be defined as the type of inheritance in which the trait or mutation is present on X chromosomes rather than on autosomes. Sex linked trait expression will depend upon the type of sex.
Two type of inheritance of sex linked trait are X linked dominant and X linked recessive trait. In X linked recessive trait, the male are more affected as they have only single X chromosome. Females should have both X chromosome affected for the expression of the trait. In sex linked dominant trait, a single X chromosome is enough for the expression of trait.
For example: Color blindness is an sex linked recessive trait, the mother generally passes the trait to their sons. Fragile X syndrome is a sex linked dominant trait in which the affected father will have all the affected daughter.

In biology, the strain is a low-level taxonomic rank used in different contexts:
In microbiology, a strain is a part of a bacterial species different from other bacteria of the same species by a minor but identifiable difference. Strains are often created in the laboratory by mutagenesis existing strains or wild-type examples of bacterial species.
In zoology, a strain corresponds to an individual or group of individuals who are at the origin of a line of descendants, sometimes called the holotype, paratypes, etc. A strain is a population of organisms that descends from a single organism or pure isolate culture. Strains of the same species may differ slightly from each other in many respects.
A strain thus consists of a group of organisms of the same species possessing certain differential traits based on their relationship; either they come from the same region, as the same watershed of a river, or they are the fruit of a particular breeding program (exists as a whole interbreeding without introductions from external sources).
