Vedclass · Answer

(C) test cross is defined as the cross of an $F_1$ hybrid with its homozygous recessive parent to determine the genotype of the $F_1$ individual.In a monohybrid test cross (e.g.,$Tt 	imes tt$),the offspring are produced in a $1:1$ ratio,where $50\%$ of the individuals exhibit the dominant trait and $50\%$ exhibit the recessive trait.Therefore,the Assertion is correct because it accurately defines a test cross.However,the Reason is incorrect because recessive individuals are indeed obtained in a monohybrid test cross.

Assertion: Cross of $F_1$ individual with recessive homozygous parent is test cross.
Reason: No recessive individuals are obtained in the monohybrid test cross.
