To determine the different types of gametes produced by a pea plant with the genotype $AaBb$,with which genotype should it be crossed?

In Mendel's dihybrid cross,how many seeds out of the $F_2$ generation ratio of $9:3:3:1$ were found to be round?

What is the genotypic ratio of the $F_2$ generation in Mendel's dihybrid cross?

In a dihybrid cross between $AABB$ and $aabb$,the $F_2$ generation produces offspring with genotypes $AABB$,$AABb$,$AaBB$,and $AaBb$. What will be their phenotypic ratio?

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?

What is the expected percentage of $F_2$ progeny with yellow and inflated pod in a dihybrid cross experiment involving pea plants with green-coloured,inflated pods and yellow-coloured,constricted pods (in $\%$)?
