The phenotypic ratio of a dihybrid test cross performed by Mendel is ....

$A$ self-fertilizing trihybrid plant forms:

In Mendel's dihybrid cross experiment,out of $16$ offspring,how many offspring possess the genotype $rrYy$?

In humans, brown eyes $(B)$ are dominant over blue $(b)$ and dark hair $(D)$ are dominant over red hair $(d)$. A man with brown eyes and red hair marries a woman with blue eyes and dark hair. They have two children; one resembles the man (brown eyes, red hair), and the other resembles the woman (blue eyes, dark hair). What are the genotypes of the man and the woman?

In Mendel's dihybrid cross,what percentage of the total $F_2$ progeny had green seeds (in $\%$)?

In Mendel's dihybrid cross,what percentage of the $F_2$ generation possesses the $RrYy$ genotype (in $,\%$)?
