In which species would you expect genetic drift to cause greater variation in allele frequencies from generation to generation? Split Grizzle G//+ (typical Grizzle), Grizzle G//G (near white pigeon) is lethal in the homozygous form. Genes located near one another on the same chromosome are often inherited together.
