Question

A common test to find the genotype of hybrid is by

• A. Crossing of one F${}_2$ progeny with male parent
• B. Crossing of one F${}_2$ progeny with female parent
• C. Studying the sexual behaviour of F${}_1$ progenies
• D. Crossing of one F${}_1$ progeny with male parent

Answer 1

Answer: (D)

Crossing of one F${}_1$ progeny with male parent

To find the genotype of a hybrid, test cross is performed in which an organism showing dominant phenotype is crossed with the recessive parent instead of selfing. The progenies of such cross can easily be analysed to predict the genotype of the test organism.

So, the correct answer is 'Crossing of one F1 progeny with male parent'.
