As you can see in the picture presented below, the three classes of water have distinctive traits.
Pure substances contain only one element, they are not mixtures of different things.
The homogeneous mixtures have multiple elements, but they are so well blended together that you can't easily observe or separate them.
In heterogeneous mixtures, we can easily differentiate between different elements of the mixture.

A

If the shape of radish is under the control of one gene, for example A than we can say:
AA is dominant homozygous genotype-round radish phenotype,
aa is recessive homozygous genotype-long radish phenotype
If we cross round and long radish:
P: AA x aa
F1: Aa Aa Aa Aa
Aa is heterozygous genotype-oval phenotype
If we than cross the F1:
Aa x Aa
F2: AA Aa Aa aa
This means that the ratio between the phenotypes woul be 1:2:1 (round:oval:long).
So that the correct amount of each protein is made.
