7. Linkage Data for Chocolate, group 2. (?)

Ch V₄  CB  71  66  42  76  255  42%

I have some later material of the same sort for more data.

With a₂ [Chrom. 5] I had only F₂ material (furnished by Clokey, segregating also for c, r), but it gives absolutely no indication of linkage.

Some miscellaneous linkage data with Ch are all negative. The earlier indication of linkage with T5-7c is washed out with further data. E. G. Anderson. [See discussion in Linkage Summary, p. 51.]
