Answer:
The distance between A and B is less than the distance between B and C.
Explanation:
Crossing over is the exchange of genetic segments that occurs between the chromatids of homologous chromosomes during prophase I of meiosis I. The process of crossing over requires the genes to be present on different chromosomes.
Linked genes are the ones that are present on the same chromosome. Linked genes that are present far apart on the same chromosome may undergo crossing over but the genes present close to each other on the same chromosome are least likely to undergo crossing over. Therefore, the frequency of crossing over increases with increased distance between the genes.
According to the given information, crossing over frequency between genes A and B is 0.1 while that for the genes B and C is 0.3. Since the genes B and C have more crossing over frequency, they are located far apart from each other than the genes A and B. Distance between A and B genes is less than the distance between B and C genes.
Answer:
For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a). This is considered a "positive" test result, and in this case indicates the presence of a functional group that can be oxidized (alcohol or aldehyde).
<span>If all of geologic time is represented as a single year, and the Jurassic period is in the middle of the Mesozoic era, than dinosaurs would be most abundant on the planet during the month of <u>December</u>. This is because the Mesozoic Era as an interval of geological time took place from about 252 to 66 million years ago, while earth's time scale is about 4.54 billion years old, and all of geological time even older. Compared to all of the geological time, dinosaurs are fairly recent.</span>
