In a dihybrid cross,what is the proportion of $RrYy$ offspring obtained from the selfing of an $RrYy$ plant (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?

In a plant,red fruit $(R)$ is dominant over yellow fruit $(r)$ and tallness $(T)$ is dominant over shortness $(t)$. If a plant with $RRTt$ genotype is crossed with a plant that is $rrtt$,what will be the phenotypic ratio of the offspring?

What type of gametes will be formed by the genotype $RrYy$?

How many types of gametes are produced in the $F_1$ generation of a trihybrid cross?

In Mendel's experiments with garden pea,round seed shape $(RR)$ was dominant over wrinkled seeds $(rr),$ and yellow cotyledon $(YY)$ was dominant over green cotyledon $(yy).$ What are the expected phenotypes in the $F_{2}$-generation of the cross $RRYY \times rryy$?
