Eeek, *scratches head and tries to remember probability theory*

If I read correctly you are talking about independant events so the result of one event doesn't change the odds of the next.

Both statements can be true. On average, over time, you would expect the data to be distributed 50/50. But everything is a possibility, it just isn't probable. So it is true that the overall percentages could be everything but the probability of 80/20 is smaller than 50/50. But still possible.

Here is one person's results. Remember these are not real sheep. *We bred the same pair of animals 12 times: the yellow ram with blue stars + violet ewe with white stars. * *Of the ***12 offspring, 9 were plain**. 3 were patterned: two were exact copies of the father (yellow ram with blue stars), and one was exact copy of the mother (violet with white stars).
So the question is...should the results have been closer to 6 plain and 6 patterned? |

Sample size isn't really big enough. If you toss a coin 10 times you might get 8 heads and 2 tails. You are far less likely to get 800 heads and 200 tails if you toss the coin 1000 times.

Over time you would expect the data to settle closer to the 50/50 mark.
