How many different types of gametes can be produced by the $F_1$ progeny resulting from the cross $AA BB CC \times aa bb cc$?

$A$ cross was made by Mendel with pea plants between violet flowers $(VV)$ in axial position $(AA)$ and white flowers $(vv)$ in terminal position $(aa)$. What phenotypic ratio of white flowers $(vv)$ did he receive in the $F_2$ generation (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?

Mrs. Verma has a pair of autosomal genes '$Bb$' and she also carries an $X$-linked gene '$dd$'. What will be the percentage of gametes that contain the genes '$bd$'?

In Mendel's dihybrid cross experiment,what is the phenotypic ratio of the progeny obtained from a test cross of the $F_1$ generation?

What is the phenotypic ratio of a test cross in the $F_1$ generation of a dihybrid cross?
