How CONSTANS gene and its encoded protein involved in translating day length into a signal that converts a vegetative shoot meristem into a floral meristem?

#I Life Science/ Life Sciences Group – I-V
  1. CONSTANS protein is degraded in the dark, but accumulates in the leaves as the days get longer.
  2. CONSTANS protein is degraded in the light, and so accumulates in the leaves as the days get shorter.
  3. Peak expression of CONSTANS occurs at mid-morning.
  4. The CONSTANS gene regulates the circadian clock.

You perform the three different two-factor crosses (Cross 1: XY and xy, Cross 2: YZ and yz, and Cross 3: XZ and xz). Assume all crosses are between diploid flies homozygous for the alleles of these genes. You observe 7% recombinants in the first cross, 20% recombinants in the second cross, and 13% recombinants in the third cross. if cross between XyZ and xYz leads to which of the followining recombinant with double cross over .
