When a pure tall pea plant with green pods is crossed with a dwarf plant with yellow pods, how many $F_2$ offspring out of $16$ will be tall?

In a dihybrid cross between individuals with genotypes $TtRr$,if the total number of offspring is $16$,identify the number of individuals with genotypes $TtRr$ and $TtRR$ among them.

The Mendel dihybrid phenotypic ratio is . . . . . . .

When a dwarf plant with terminal flowers is crossed with a tall plant with axial flowers,what will be the proportion of dwarf plant progeny in the $F_1$ generation (in $\%$)?

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