How many different kinds of gametes may be produced by an organism with the genotype $RrYy$?

The gametes of an individual with genotype $AaBb$ can be:

When a cross is made between a tall plant with yellow seeds $(TtYy)$ and a tall plant with green seeds $(Ttyy)$,what proportions of phenotypes in the offspring could be expected to be:
$(a)$ Tall and green.
$(b)$ Dwarf and green.

Explain the Law of Independent Assortment based on a dihybrid cross.

In a cross between $AABB$ and $aabb$,what is the probability of obtaining $AaBb$ in the $F_2$ generation (in $/16$)?

How many different types of gametes can be formed by $F_1$ progeny,resulting from the following cross: $AA BB CC \times aa bb cc$?
