A. codominance
B. incomplete dominance
C. mutation
D. linkage

Correct Answer:

Option B – incomplete dominance


Incomplete dominance

this is the ability of two contrasting alleles to interact and produce a heterozygous phenotype that is different from the two homozygous phenotypes

example: a pure breeding red flower Mirabilis Jalapa when crossed with a pure breeding white-flowered plant produce F1 plants that bear pink flowers.

it was Mendel that proposed it

RR= red

rr= white

if you cross them, f1 generation will all be pink flowers
