In the $F_2$ generation of a dihybrid cross,what is the probability of a plant being homozygous for both dominant traits (in $/16$)?

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 experiments with garden pea,round seed shape $(RR)$ was dominant over wrinkled seeds $(rr)$,and yellow cotyledon $(YY)$ was dominant over green cotyledon $(yy)$. What are the expected phenotypes of the $F_1$ generation when a homozygous round yellow plant $(RRYY)$ is crosseded with a homozygous wrinkled green plant $(rryy)$?

$F_{1}$ progeny of a Mendelian dihybrid cross produces:

$A$ dihybrid condition is represented by:

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