The sentence that best explains why the native Australian dung beetles were not doing the job is "Cow dung is not part of any native Australian species niche." The beetles in Australia had formed alongside the kangaroos and wombats. When the cattle were brought to Australia in the 1880's by European settlers, the beetles were not used to the texture of the dung. It was much different and the dung was not decomposing. Native beetles were not using this dung as a feeding source. This left the cattle not feeding in the pasture because they won't eat near the dung. This reduced the cattle grazing land.
A single gene disorder is one that's known to be caused by a single gene. Multiple gene disorders, however, can be caused by multiple gene combinations and other factors. Dominant genes are always expressed in the offspring, while recessive genes are only expressed if the offspring recieves the recessive gene from both parents. Sex-linked genetic disorders occur most often in men, and are caused by a single-gene disorder gene being on the X chromosome but not the Y, so that the offspring needs only one recessive gene to have the trait/disorder.

C. Law of segregation is the Mendel's law that states that gametes carry one allele for each trait.
