Hi,
Since you are asking about solutions then let's stick to solutions.
Homogenous Solution ["homo" Latin for "all the same"] An example of this is NaCl solution added to pure water. Since the two liquids are similar in many properties, the pure water will invade the NaCl solution until it is evenly diluted.
Heterogenous Solution ["hetero" Latin for "different...not the same"] An example of this would be oil added to water. Since the water is more dense and the water is polar (charged) and the oil is non-polar (uncharged) then the oil will "float" on the water and not mix.
Now both of these things can be altered to make either case have opposite properties:
In the first example: we can change the properties of one of the liquids to make it dis-similar enough that they do not easily mix. Make the salt water very cold ... say 30F and the pure water at room temp they will resist mixing.
In the second example: we can use a emulsifyer (an item that has a polar end of the molecule and a non-polar end) This acts to allow microdrops of oil to easily and completely mix with water.... such as egg white in pure cooking oil (mayonase) will mix with water. The egg white is the emulsifyer that allows a homogenous solution to happen.

a homogenous solution is one that is completely mixed evenly, think like, for example, a glass of koolaid. no matter where in the glass you take a sample, it will all have the same amounts of coloring, flavor, water and sugar.
a heterogenous solution is one that is not evenly mixed. in some areas there will be more of one thing than the other. take, for example, a sample of the earth. some layers have more limestone, some have granite, some of tons of minerals, some not. it is NOT evenly mixed, therefore it is heterogenous.

do you mean homozygous and heterozygous?
heterozygous parents: QqxQq
`````Q | q
`Q|QQ|Qq|
`q |Qq |qq |
homozygous offspring: QQ and qq
