nexus9112 [7]

Answer:

<em>The correct option is Although the F1 generation will all show the dominant trait, the offspring  will all be heterozygous and increase chances of future variation.</em>

Explanation:

The cross for the offsrings that will be produced by F1 generation is shown below:

         a          a

A      Aa       Aa

A      Aa        Aa

As we can see that all the offsprings in the F1 generation will have heterozygous genes but only the dominant trait will be seen in the phenotype of the F1 generation.

A cross between the F1 generation will give the following results:

         A          a

A      AA      Aa

a       Aa      aa

This cross shows that there will be increases genetic and phenotype variations in offsprings that will be produced by the F1 plants.
