Pioneer species include bacteria and lichens that can grow on bare rock and help make soil. Secondary succession occurs in a formerly inhabited area that was disturbed. Soil is already in place, so pioneer species include small plants such as grasses.
It basically means the oldest rocks and newest rocks are organized from top to bottom, like a bunk bed, oldest at the bottom, newest at the top in chronological order.
When you cross two hybrids, the results always come in a 3:1 ratio as follows:
3 is the inheritance of at least 1 dominant allele
1 is the inheritance of two recessive alleles
Punnet Squares are very useful!
<u>T t </u>
T | TT | Tt |
t |<u> Tt | tt </u>|
Three out of 4 boxes have offspring that express the dominant trait (tall plants) and 1 out of 4 boxes expresses only the recessive trait (short plants).
Hope this helps! :)
