Develop a scenario with a Punnett Square and discuss how the offspring outcomes change if the gene
expression is governed by:
o Dominant/recessive genes
o Codominance
o Incomplete Dominance

Answer 1

Answer:

o Dominant/recessive genes

Cross: Rr   x   Rr  (two round-seeded plants)

F1) 25% RR, 50% Rr, 25% rr

    75% Rounded seeds, 25% elongated seeds

o Codominance

Cross: BB   x   WW (black chicken with white chicken)

F1) 100% BW

    100% speckled chickens

o Incomplete Dominance

Cross: RR   x   rr   (Red-flowered plant with white-flowered plant)
