The correct answer is: B) The F1 variance is due only to environmental factors.
According to Mendelian genetics: he crossed two purebred parents with differing traits to be sure that there were no other factors contributing to the outcome of the cross. When two purebred parents are crossed, all of the offspring should be genetically the same (heterozygous).
In the example above, we can see that there is phenotypic variance among the offspring, so we can conclude that it must be due only to environmental factors.
