Title

Marjorie P. Maguire CYTOLOGIA 1962. doi:10.1508/cytologia.27.248
Other claims from this paper (6)
- Observation In corn, longer chromosome arms have greater variances.
- Observation In corn, longer chromosome arms have smaller coefficients of variability.
- Observation In corn, chromosomes with larger arm ratios have more variable arm ratios.
- Association In corn, variabilities in arm ratio are not correlated with variabilities in chromosome length.
- Intervention effect Tripsacum chromosome material does not differ in length variability from the corresponding corn chromosome material it replaces.
- Mechanism Chromosomes of corn have two kinds of variability, one contributing uniformly per unit length and one a property of each chromosome.
