Law of dominance: The cross between the pea plants differing in single pair of contrasting characters is known as monohybrid cross. Mendel made a monohybrid cross between tall and dwarf pea plants then only tall pea plants appeared in the first filial generation(F1). But when the F1 progeny were allowed to be self fertilized, both tall and dwarf characters appeared in the second filial generation or F2.
Law of segregation: The law of segregation is also known as law of purity of gametes. The law states that the hybrids or heterozygotes of F1 generation have two contrasting characters or allelomorphs of dominant and recessive nature.
