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.
Males average approximately 44 words per minute, while females average 37 words per minute. The average of the two is 41 words per minute. Handwriting is estimated to reach slightly more than 30 words per minute, which shows that average typing is still faster than handwriting.
