Experimental support for Mendel's law of segregation comes from the results of self-fertilizing F2 plants that display the dominant phenotype. Based on the law of segregation, what proportion of the dominant F2 plants would be expected to produce F3 progeny phenotypes in a ratio of 3 dominant : 1 recessive?
