Expert Solution
Step 1

The cross between two individuals when performed by taking one pair of character (allele) is known as monohybrid cross.

For example, Cross between T//Tx T/t ( T= tall gene, t= dwarf gene)

The cross between two individuals when performed by taking two pairs of characters (alleles) is known as dihybrid cross. For example, Cross between a yellow-round seed pea plant and green-wrinkled seed pea plant.
