Observation The Xa xa genotype of the xanthophyllous tomato mutant is viable.
Observation The expected 1: 2: 1 genotype ratio is never realized in the progeny.
Observation Under good germination conditions the xanthophyllous progeny ratio is 2: 1.
Observation Under poor germination conditions the xanthophyllous progeny ratio may approach 1: 1.
Method / resource Maximum likelihood linkage formulae give results similar to the simple product moment method for these data.
Observation Xa is in tomato linkage group VII (chromosome 10).
Observation The lethal effect of Xa disturbs the monogenic ratios of all genes in linkage group VII.
Observation Crossover value between Xa and H is 44.5%.

Observation Crossover value between Xa and t is 35.5%.
Observation Crossover value between Xa and t v is 31.7%.
Observation Crossover value between Xa and ag is 46.5%.
Association Under standard growing conditions, xanthophyllous tomato has less chlorophyll than green (790 vs 3240 μg./g.).
Association Under standard growing conditions, xanthophyllous tomato has less xanthophyll than green (54 vs 211 μg./g.).
Association Under standard growing conditions, xanthophyllous tomato has less carotene than green (60 vs 130 μg./g.).
