$Y$-linked gene modification
In pea plants, red flowers $(R)$ are dominant over to white flowers $(r)$ and tall plants $(T)$ are dominant over to dwarf plants $(t)$. The table below shows the gametes and the possible offsprings 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 offsprings produced will be homozygous for both the recessive characters
