Answer:
Frequency of individuals with recessive trait(dd)
%
Explanation:
Please see the attached.
In the image it is clear that there are total 
mouse out of which 
are dark colored.

Answer:
FALSE
Explanation:
Ionization energy is the minimum amount of energy required to discharge an electron from its orbital shell from an atom in ground electronic state. The closer the electron, that is to be discharged, is to the nucleus of the atom, the harder to remove it hence has high ionization energy. In addition, if the nucleus of the atoms has a higher mass and the electron is even closer, the higher the ionization energy.
