A Punnett square is a ​ (a)   that allows you to easily determine the expected ​ (b)   of different ​ (c)   in the ​ (d)   of two parents. An example of a Punnett square for pea plants is shown here. In this example, both parents are ​ (e)   for flower color (Pp).

In a broad sense, the term "genotype" refers to the ​ (a)   of an organism; in other words, it describes an organism's ​ (b)   . In a more narrow sense, the term can be used to refer to the ​ (c)   , or variant forms of a ​ (d)   , that are carried by an organism.

• complete set of genes
