A Punnett square is also used to determine the phenotypic ratio of the offspring. A phenotypic ratio is the ratio of visible traits displayed in the offspring. The Punnett square in Figure 4 shows the different allele combination and the phenotypic ratio that will result when two heterozygous parents are crossed.
The average typing speed is 38-40 words per minute (wpm) for adults in a professional working environment (despite many incorrect reports on the web that it is 50-60 wpm). <br /> <br /> Some administrative assistants can type 70-80 wpm or more.
As you progress, your speed naturally increases. The average wpm at which many people type is 31 to 41 while professional typists have a 42 to 54 wpm speed. The two highest levels of typing, known as typemaster and megaracer, have wpm speeds that range from 55 to 79 and 80+, respectively.
