From a cross $AABb \times aaBb$,the genotypes $AaBB : AaBb : Aabb : aabb$ will be obtained in the following ratio:

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

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 $\%$)?

In the cross $AABb \times aaBb$,the ratio of progeny $AaBB : AaBb : Aabb : aabb$ is:

What is the percentage of recessive gametes produced by $YyRr$ (in $\%$)?
