A gardener produces new plants using tissue culture and cuttings from the same parent. Plants from both methods are divided between dry and well-watered conditions. No mutations occur.
Which prediction about the resulting plants is correct?
Both methods preserve the parent's genes, but water availability may produce differences in phenotype.
Both methods preserve the parent's genes, so water availability cannot produce differences in phenotype.
Both methods mix genes from two parents, but water availability may produce differences in phenotype.
Both methods mix genes from two parents, so water availability cannot produce differences in phenotype.
