Vedclass · Answer

(A) To determine the unknown genotype of a dominant phenotype (black seed),a test cross is performed.$A$ test cross involves crossing the individual with the dominant phenotype with a homozygous recessive individual.Since white seed color $(bb)$ is recessive,crossing the black seed plant with a plant having the $bb$ genotype will reveal whether the black seed plant is homozygous $(BB)$ or heterozygous $(Bb)$.

In a plant,black seed color $(BB / Bb)$ is dominant over white seed color $(bb)$. In order to find out the genotype of the black seed plant,with which of the following genotype will you cross it?
