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

In Mendel's pea plants,round seeds $(RR)$ are dominant over wrinkled seeds $(rr)$,and yellow cotyledons $(YY)$ are dominant over green cotyledons $(yy)$. What will be the phenotypic ratio in the $F_2$ generation of a cross between $RRYY$ and $rryy$?

In a dihybrid cross,$80$ plants are obtained. The ratio of homozygous and heterozygous plants shall be:

When a dihybrid plant with dominant traits of red color and tall height $(RrTt)$ is crossed with a recessive plant having white color and dwarf height $(rrtt)$,what will be the phenotypic ratio of the offspring for red-tall,red-dwarf,white-tall,and white-dwarf respectively?

In a dihybrid cross between $RRYY$ and $rryy$,what is the probability of obtaining $RrYy$ in the $F_{2}$ generation (in $/16$)?

In plants,red color $(R)$ is dominant over yellow $(r)$ and tallness $(T)$ is dominant over dwarfness $(t)$. If a plant with genotype $RRTt$ is crossed with a plant with genotype $rrtt$,what will be the result?
