The Smith family is afflicted with a genetic disorder known as Pinocchio nose syndrome, which causes affected adults to grow nos
es in excess of five inches long. 100 members of the Smith family show up for a family reunion. Of the fifty-three women, thirty-seven have unusually large noses. Of the forty-seven men, thirty-six have an enormous nose. Based on these figures, Pinocchio nose syndrome is probably A) dominant and sex-linked.
B) recessive and sex-linked.
C) dominant, but not sex-linked.
D) recessive, but not sex-linked.
The disorder is not sex-linked because almost equal numbers of people have Pinocchio nose syndrome. If the disorder was sex linked you would have way more men than women having the disorder.
You can tell that the genetic disorder is dominant because there is a 3:1 ratio for those who have the disorder.
36 out of 47 men ≈0.765
37 out of 53 women≈0.69
These numbers approximate a 3:1 ratio (even if it's not exact), meaning that the disorder is most likely dominant
An organelle is the word that scientists use to describe a part of a cell that is enclosed by a membrane. A lysosome, nucleus and a mitochondria are all examples of organelles.
Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. ... There, the recombinant bacteria use the gene to begin producing human insulin. Scientists harvest the insulin from the bacteria.
