In a dihybrid cross,$80$ plants are obtained. The ratio of homozygous and heterozygous plants shall be:

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?

If two pairs of genes are represented by $AA, Bb$,what are the possible gametic combinations after meiosis?

In Mendel's dihybrid cross experiment,out of $16$ offspring,how many offspring possess the genotype $rrYy$?

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?
