The researcher determines that an average nest incubation temperature of 32 – 33?C results in the birth of male crocodiles, while higher and lower incubation temperatures result in female crocodiles. What is the most likely explanation for this phenomenon?
A. Since this phenomenon is influenced by an external stimuli (temperature), it cannot be attributed to changes in either the genome or the proteome.
B. Incubation temperature changes both the crocodilian genome and proteome.
C. Incubation temperature results in a change in the crocodilian proteome.
D. Incubation temperature results in a change in the crocodilian genome.
C. Incubation temperature results in a change in the crocodilian proteome.
