Vedclass · Answer

(C) cross between an $F_1$ heterozygote (e.g.,$Tt$) and a recessive parent (e.g.,$tt$) is known as a test cross.In a test cross,the $F_1$ heterozygote produces two types of gametes: $T$ and $t$.The recessive parent produces only one type of gamete: $t$.Performing a Punnett square: $(T, t) 	imes (t)$ results in offspring with genotypes $Tt$ and $tt$ in a $1:1$ ratio.Therefore,the phenotypic and genotypic ratio is $1:1$.
