NEETBiologyPrinciples of Inheritance and VariationMCQ+4 / −1
A cross in which an organism showing a dominant phenotype in crossed with the recessive parent in order to know its genotype is called -
  1. A
    Dihybrid cross
  2. B
    Back cross
  3. C
    Monohybrid cross
  4. D
    Test cross
View written solutionFree

Correct answer: D

Test cross is performed to determine the genotype of F2 plant. In a typical test cross an organism showing dominant phenotype and whose genotype is to be determined is crossed with one that is homozygous recessive for the allele being investigated, instead of self-crossing. The progenies of such a cross can easily be analysed to predict the genotype of the test organism.
