Vedclass · Answer

(B) This cross is a classic example of a dihybrid test cross.In a dihybrid test cross,a dihybrid individual $(YyRr)$ is crossed with a homozygous recessive individual $(yyrr)$.The dihybrid parent $(YyRr)$ produces four types of gametes: $YR$,$Yr$,$yR$,and $yr$ in equal proportions.The homozygous recessive parent $(yyrr)$ produces only one type of gamete: $yr$.When these gametes fuse,the resulting offspring genotypes are $YyRr$,$Yyrr$,$yyRr$,and $yyrr$ in a $1:1:1:1$ ratio.These genotypes correspond to the phenotypes: Yellow-round,Yellow-wrinkled,Green-round,and Green-wrinkled,respectively.Therefore,all four phenotypes are produced in equal proportions.
