dihybrid cross? - answer-A dihybrid cross involves organisms that are
heterozygous for two characters that are being studied, and a
monohybrid cross involves organisms that are heterozygous for only
one character being studied.
What was the most significant conclusion that Gregor Mendel drew
from his experiments with pea plants? - answer-Traits are inherited
in discrete units and are not the results of "blending."
