$A$ cross between one tall plant and one dwarf plant resulted in offspring having tall plants. What would be the genotype of offsprings?

When experimenting with the factor of tallness in $Pisum$ $sativum$,Mendel obtained the results $73.97\%$ tall and $26.03\%$ dwarf from one of the crosses. This shows that the parents are:

If a dwarf plant is treated with gibberellin,it becomes tall. If this plant is now crossed with a pure tall plant,what will be the progeny of the $F_1$ generation?

How many different types of gametes will be produced by a plant with the genotype $AABbCC$?

Which of the following is not observed in a monohybrid cross?

In a plant,black seed color $(BB / Bb)$ is dominant over white seed color $(bb)$. In order to find out the genotype of the black seed plant,with which of the following genotype will you cross it?
