In an attempt to breed winter barley that is resistant to barley mosaic virus, agricultural researchers cross a susceptible domesticated strain with a resistant wild strain. The F1 plants are all susceptible, but when the F1 plants are crossed with each other, some of the F2 individuals are resistant. Is the resistance allele recessive or dominant? (Note: susceptible means able to get the viral disease, while resistant means not able to get the disease) A) The resistance allele must be recessive B) The resistance allele must be dominant
