4. Yellow seedlings appear to grow faster and die sooner than albino seedlings. The albinos lived about 21 days at 80F and the yellows about 18 days. These were in sister progenies. To be sure of any trend or relationship one would need to study the life span of the yellow and albino seedlings in a progeny where they coexist. I have such progenies. The ratio in progenies not marred by embryoless is 9 green : 3 yellow : 4 albino. Could the carotene have an accelerating effect on food consunption and growth rate?
