Vedclass · Answer

(A) test cross is a cross between an individual with a dominant phenotype (whose genotype is unknown) and a homozygous recessive individual. If the offspring show a $1:1$ ratio of dominant to recessive phenotypes,the parent is heterozygous. If all offspring show the dominant phenotype,the parent is homozygous dominant. Therefore,a test cross is the standard method to determine the genotype of an organism showing a dominant trait.

The genotype of a plant showing a dominant phenotype can be determined by:
