◉A ___________ trait or continuous trait is an inherited trait that
exhibits many intermediate forms; determined by segregating alleles
of many different genes who interaction with one another and the
environment produces the phenotype. Answer: Quantitative

phenotype, the gene is said to show complete ___________. Answer:
Penetrance

expression of a phenotype is ___________. Answer: Epistasis
, ◉Which of the following diseases show pleiotropism? Answer:
Sickle Cell Anemia

by counting and/or controlled crosses, is seen in which of the
following terms? Answer: Penetrance and Expressivity
◉Which of the following ratios shows incomplete dominance?
Answer: 1:2:1
