NEETBiologyPrinciples of Inheritance and VariationMCQ+4 / −1
Two crosses between the same pair of genotypes or phenotypes in which the sources of the gametes are reversed in one cross, is known as : -
  1. A
    Reciprocal cross
  2. B
    Reverse cross
  3. C
    Test cross
  4. D
    Dihybrid cross
View written solutionFree

Correct answer: A

A reciprocal cross means that the same two parent are used in two experiments in such a way that if in one experiment A is used as the female parent and B is used as the male parent then in the other experiment A will be used as the male parent and B as the female parent. Thus the sources of gametes are reversed. When the F1 individuals obtained in a cross is crossed with the recessive parent, it is called a test cross. When inheritance of two pairs of contrasting character is studied simultaeneously it is called dihybrid cross.
