In the second generation, the dwarf trait reappears during Mendel’s experiment in monohybrid cross. Why so?

Answer :

• In mendelian inheritance, one trait is dominant and other is recessive.


• Recessive trait cannot express itself in presence of dominant trait in First generation.


• In the first generation plants, recessessive gene (factor) is present in their genome but does not show its effect.


• When this first generation plants plants are crossed. The recessive gene separate form dominant gene during gamete formation.


• The recessive gene move to one gamete and dominant allele to another gamete.


• When male gamete containing recessive gene fuse with the recessive gene of female gamete for same trait in the second generation, the allele combination will become fully recessive and make the phenotype dwarf for the plant height character.


• Recessive trait appears only in in its homozygous condition. Threfore, dwarf trait reappears during second generation in Mendel's Monohybrid cross.


• Crossing of First generation plants:



(tt) is the recessive plant reappers in the second generation.
