A) PKG influences food-related behaviors in a wide variety of animals.
B) There is enormous variation in amino acid sequences between taxa.
C) There is likely a conserved evolutionary relationship between these genes and their behavioral phenotype.
D) PKG influences food-related behaviors in a wide variety of animals,and there is enormous variation in amino acid sequences between taxa.
E) PKG influences food-related behaviors in a wide variety of animals,and there is likely a conserved evolutionary relationship between these genes and their behavioral phenotype.
