The gametes of an individual with genotype $AaBb$ can be:

In $F_2$ generation,a phenotypic ratio of $1:1:1:1$ exhibits

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 Mendel's dihybrid cross experiment,how many types of genotypes are obtained in the $F_2$ generation?

Which one of the following crosses will have a $1:1:1:1$ ratio of progeny?

How many types of gametes are produced by a dihybrid plant?
