Vedclass · Answer

(A) test cross is defined as the cross between an individual of unknown genotype (usually $F_1$ hybrid) and a homozygous recessive parent.In a monohybrid cross,the $F_1$ hybrid has the genotype $Tt$.The homozygous recessive parent has the genotype $tt$.The cross is represented as: $Tt 	imes tt$.The resulting offspring are $Tt$ (tall) and $tt$ (dwarf) in a ratio of $1 : 1$.Therefore,the phenotypic ratio obtained from a test cross of $F_1$ progeny is $1 : 1$.

What is the phenotypic ratio obtained from a test cross of $F_1$ progeny in a monohybrid cross?
