JAMB Biology 1978 Question 49

In a breeding programme a cross was made between two true-breeding cowpea types: one with round seeds and the other with wrinkled seeds. If roundness is dominant while wrinkleness is recessive, in the first filial generation all the seeds produced will be

1. A.25 per cent wrinkled, 75 per cent round
2. B.100 per cent wrinkled
3. C.50 per cent wrinkled, 50 per cent round
4. D.75 per cent wrinkled, 25 per cent round
5. E.100 per cent round.
