Question

In the first step of monohybrid cross experiment, Mendel selected pea plants which were

• A. Pure tall as male and pure dwarf as female
• B. Pure tall as female and pure dwarf as male
• C. Heterozygous tall as male and pure dwarf as female
• D. Heterozygous tall as female and pure dwarf as male

Answer 1

The correct option is B Pure tall as female and pure dwarf as male

Mendel performed cross-breeding experiments on garden pea (Pisum sativum). He studied the inheritance of seven different pairs of contrasting characters in this plant but considered only one pair at a time. He crossed two pea plants having contrasting characters (for example tall and dwarf pea plants) by artificial pollination and obtained the hybrids. The resulting hybrid plants were then crossed with each other. He obtained the data from these crosses and analysed the results carefully.

In the first cross, a pure tall female was crossed with a pure dwarf male

So, the correct answer is 'Pure tall as female and pure dwarf as male'
