How many different types of gametes will be formed by a pea plant with genotype $TtYy$?

In plants,red fruit $(R)$ is dominant over yellow fruit $(r)$ and tall height $(T)$ is dominant over dwarf height $(t)$. If a plant with genotype $RRTt$ is crossed with a plant with genotype $RRTt$,what will be the phenotype of the offspring?

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 dihybrid cross,what is the proportion of the dominant homozygous plants in the $F_2$ generation (in $/16$)?

Pure homozygous offsprings in a dihybrid cross in the $F_2$ generation will be

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 $\%$)?
