Q.
A white pea plant is crossed a heterozygous violet pea plant. What will be characteristic of offspring?
NTA AbhyasNTA Abhyas 2020Principles of Inheritance and Variation
Solution:
In a typical test cross, an organism (pea plants here) showing a dominant phenotype (and whose genotype is to be determined) is crossed with the recessive parent instead of self-crossing. The progenies of such a cross can easily be analysed to predict the genotype of the test organism.
