Monohybrid cross :
A cross between parents differing in only one heritable trait is called monohybrid cross. e.g. cross of pure tall and pure dwarf plants. Mendel performed the monohybrid cross between two pea plants with only one pair of contrasting character.
Dihybrid cross :
A cross between parents differing in two heritable traits, is called dihybrid cross e.g. cross of pure tall, round seeded plant with dwarf, wrinkled seeded plant. Mendel also performed the dihybrid cross between pea plants that differed in two pairs of contrasting characters.
