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.]
