The effect of varying gene dosage on aleurone colour in maize

  • Published:
Journal of Genetics Aims and scope Submit manuscript

Conclusion

1. A new dominant geneDt interacts with recessivea 1 in the presence of the dominant allels of the other factors concerned with aleurone colour to give coloured dots scattered over the aleurone layer.Dt is specific in its interaction with recessivea 1.

2. The effect on the dotted character of varying the dosage of recessivea 1 was additive. Data on three dosages ofa 1 were obtained.

3. The effect on the number of dots of varying the dosage of theDt gene was non-additive.
