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

In a dihybrid cross between $AABB$ and $aabb$,the $F_2$ generation produces offspring with genotypes $AABB$,$AABb$,$AaBB$,and $AaBb$. What will be their phenotypic ratio?

Which law did Mendel propose based on his dihybrid cross experiment?

In Mendel's experiment with garden peas,round seeds $(RR)$ were dominant over wrinkled seeds $(rr)$. Yellow cotyledons $(YY)$ were dominant over green cotyledons $(yy)$. What will be the phenotypic ratio of the $F_2$ generation produced by crossing $RRYY \times rryy$?

How many types of gametes will be produced by a genotype $AABbCc$?

How many types of gametes may be produced by genotype $D/d : E/e : F/f$?
