Question

A heterozygous round seeded plant is crossed to recessive wrinkled seeded plant. The progeny would be

• A. 303 rounded : 301 wrinkled
• B. 301 rounded : 100 wrinkled
• C. 20 rounded : 99 wrinkled
• D. 99 rounded : 301 wrinkled

Answer 1

The correct option is A 303 rounded : 301 wrinkled

A heterozygous round seeded plant is crossed to recessive wrinkled seeded plant. In the next generation 50% rounded seeded plants and 50% wrinkled seeded plants are formed in 1:1 ratio. So, it is a test cross.

So, the correct option is ‘303 rounded: 301 wrinkled’.
