Professor PC Thomas Classes · Answer

(b) : When plants having two contrasting characters are crossed, $F_{1}$ generation shows dominant phenotype and the recessive phenotype is not lost but appears in $F_{2}$ generation. This suggested that there is no blending of Mendelian factors in $F_{1}$ generation but they stay together and only one of them is expressed. At the time of formation of gametes, these two factors obviously separate or segregate, otherwise recessive type will not appear in $F_{2}$ generation. The gametes which are formed are always pure for a particular character. That is why it is called as 'principle of segregation' or 'law of purity of gametes'.
