Transcribed Image Text:Wild type, winter annual accessions of Arabidopsis will flower after 20 days at 23C in long day
conditions (critical photoperiod 15 hours) following 30 days at 4C. What is the predicted flowering-
time response of each experimental plant's genotype (listed below) relative to a wild-type winter
annual accession when both are grown from seed under the following experimental conditions?
The possible flowering time responses are: EARLY, LATE, SAME relative to a wild-type winter annual
grown under the environmental conditions listed below.
