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

$A$ cross was made by Mendel with pea plants between violet flowers $(VV)$ in axial position $(AA)$ and white flowers $(vv)$ in terminal position $(aa)$. What phenotypic ratio of white flowers $(vv)$ did he receive in the $F_2$ generation (in $/16$)?

From a mating of two dihybrid individuals $(AaBb \times AaBb)$,how many of the $16$ possible zygote combinations would be expected to contain only two dominant genes?

In the $F_2$ generation of a dihybrid cross,how many plants possess the same genotype as the parental generation?

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 $1 : 1 : 1 : 1$?

In pea plants,red flowers $(R)$ are dominant over white flowers $(r)$ and tall plants $(T)$ are dominant over dwarf plants $(t)$. The table below shows the gametes and the possible offspring produced in a dihybrid cross. The numbers $1$ to $16$ represent the genotypes of each individual cross $(e.g., 3 = RrTT)$.

	$RT$	$Rt$	$rT$	$rt$
$RT$	$1$	$2$	$3$	$4$
$Rt$	$5$	$6$	$7$	$8$
$rT$	$9$	$10$	$11$	$12$
$rt$	$13$	$14$	$15$	$16$

If plant $7$ is crossed with plant $12$,then what proportion of the offspring produced will be homozygous for both the recessive characters (in $\%$)?
