A、with genes that are far apart, double crossovers and other multiple-crossover events often lead to lethal recombinants that reduce the number of recombinant progeny.
B、with genes that are far apart, double crossovers and other multiple-crossover events often lead to nonrecombinant or parental offspring and thus reduce the true map distance.
C、crossover interference will cause more double crossovers and other multiple-crossover events to occur than would be expected and thus result in a higher number of recombinant progeny than expected to occur with genes that are far apart.
D、double crossovers and other multiple-crossover events occur more often when genes are close to each other and can be readily detected, so these map distances are more accurate than those for genes that are far apart.
E、when genes are far apart, single-crossover recombinant classes are more difficult to detect than when genes are close together.

| Color is very important in our daily life. It can influence our choice of purchase when we go shopping and can also affect the way we look and feel. A person can be naturally attracted to one particular color while finding another color repulsive. The influence of color on human emotions and feelings is very powerful and designers, advertisers, artists and even doctors useitin their professions for different purposes. Every day, without even thinking about it, we use color to communicate our feelings. For example, the color we choose to wear is one way of expressing ourselves. It says something about the person, how he or she feels, and how he or she wants others to feel about the wearer. In other words, color talks. A person who wants to appear stylish and mature will usually wear dark colors or black. A person who wishes to appear youngish, pure and innocent dresses in white, like the choice of a bride's wedding gown. Also clothed in white are doctors, dentists, nurses and hospital in-patients as the color expresses comfort, cleanliness and professionalism. Brown, blue or grey clothes are the usual colors worn by office workers so as not to draw unnecessary attention to them. They are, in a way, conveying the message that they want to be noticed for their work, not their appearance. People who wear bright, strong colors like to be attractive and these colors are particularly popular with actresses, singers and party goers. In the past, common people were not allowed to wear certain colors. In Thailand, for example, only kings, queens and members of the royal family could wear purple while in ancient China, yellow was the color reserved for the emperor and the empress. Nowadays, people can wear whatever color they like or as they think appropriate. |
