➜ <u>Mendel conducted breeding experiments with garden peas</u>:
[i] He studied plants (pure) of a tall/short varities.
[ii] He crossed them and obtained F1 progeny.
[iii] He found that F1 progeny was all tall plants.
[iv] He selfed the (hybrid) plants if F1 progeny.
[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.
(or any other contrasting character may be taken).
<u>Note</u>: Here, F1 means <u>First fillial generation</u> and F2 means <u>Second fillial generation</u>.
If a snowstorm is predicted in Chicago, then the conditions should be
upper air temperature = low
surface temperature = high
air pressure = low
For a snowstorm to occur, warm air must rise above cold air. The pressure must also be below atmospheric pressure.<span />
The general shape of the epithelial cells that are nearest
to the lumen in an empty urinary bladder is in multiple cell layers which are
considered to be a stratified tissue and the cells in it are shaped in terms of
the organ’s distention. This type of epithelial cell is the transitional
epithelium.
