In Mendel's dihybrid cross,what percentage of seeds with yellow color were obtained in the $F_2$ generation (in $\%$)?

In the $F_2$ generation of a Mendelian dihybrid cross,how many plants homozygous for both the traits are found?

In the $F_2$ generation of a dihybrid cross of homozygous parents,the number of genotypes and phenotypes will be respectively . . . . . . .

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?

When a cross is made between a tall plant with yellow seeds $(TtYy)$ and a tall plant with green seeds $(Ttyy)$,what proportions of phenotypes in the offspring could be expected to be:
$(a)$ Tall and green.
$(b)$ Dwarf and green.

If the cells of an organism heterozygous for two pairs of characters,$Aa$ and $Bb$,undergo meiosis,what will be the genotypes of the gametes produced?
