Question
What is a monohybrid cross? How did Mendel perform this cross?
✓
Answer
Monohybrid cross: It is a cross where two forms of a single trait are crossed or hybridized.
Mendel performed this experiment on the pea plant. He crossed the true-breeding forms of tall and dwarf plants and obtained the hybrid progeny. This is called as first generation ($F_1$) offspring plant to self-pollinate and produced the second generation ($F_2$).

A healthy croton plant bearing variegated leaves was kept in a dark cupboard to destarch it after which it was placed in sunlight for a few hours. One of the leaves was then plucked and an outline of the leaf marking the green and the non-green regions was drawn. The leaf was then tested for starch. Using the above information, answer the following questions:
- State the aim of the above experiment.
- Name the chemical used for testing the presence of starch.
- Why is the leaf boiled in water and alcohol before testing for the presence of starch?
- What change is seen on the leaf after the starch test?
- Give the chemical equation to represent the process of starch formation in plants.
