The proportion of the two phenotypes when the F1 generation group from 10 100 offspring will remain the same.
Explanation:
The proportion of the phenotypes will remain the same as it could be calculated through Punnett square. Organism physical appearance depends upon their parent organism. The transfer of DNA from one generation to another generation plays an important role in the transfer of trade from one to another generation.
In the cell division time, the chromosomes get doubled and divided equally into the new daughter cells. These daughter cells grow up and shows the phenotype characters which is relevant to their parent’s cell.
