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

During a dihybrid cross with contrasting characters,in the $F_2$ generation,what is the proportion of individuals with parental genotypes (in $/6$)?

What is the genotypic ratio of the $F_2$ generation in Mendel's dihybrid cross?

The genotypes of a plant variety were $TtHh, Tthh, ttHh$ and $tthh$,where $T =$ tallness and $H =$ hairy stem. Which one of the following crosses would produce progeny giving a phenotypic ratio approximately $1 : 1 : 1 : 1$?

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

If two pairs of genes are represented by $AA, Bb$,what are the possible gametic combinations after meiosis?
