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! :)
You can find the air spaces in the cell of the leaves where
stoma can be located. The stoma allows
for carbon dioxide to come in, and oxygen to go out. A stoma opens into the airspace inside the
leaf. Carbon dioxide, oxygen, water vapour are the gases might you find in the
air space.
I think it is 3 instead of 4
