Because the genes are linked, the expected ratio in the f2 generation would be 50% with gray bodies and straight wings: 50% with black bodies and curved wings. but four different phenotype combinations appear in the offspring the two expected but there were also offspring with gray bodies and curved wings and offspring with black bodies and straight wings which of the following best explains what happened?
a) a mutation changed the genotype of a portion of the flies m the f2 generation.
b) a mutation changed the genotype of the f1 male's dna.
c) independent assortment resulted in the new combination of traits in the f2 generation.
d) a recombination occurred during the formation of the f1 male's sperm cells.
e) a recombination occurred during the formation of the f1 female's egg cells.
