The picture shows fruit produced by two parents and fruit produced by one of their offspring.
Which of these best describes this inheritance pattern?
(open the link attached to see the picture)
a. codominance because he fruit color of the offspring is an intermediate form of the parents’ fruit color
b. codominance because both parents’ colors are expressed in the offspring
c. incomplete dominance because both parents’ colors are both visible in the offspring
c. incomplete dominance because the fruit color of the offspring is an intermediate form of the parents’ fruit color

Answer:
incomplete dominance because the fruit colour of the offspring is an intermediate form of the parents fruit colour
Answer will be (d) incomplete dominance because the fruit color of the offspring is an intermediate form of the parents’ fruit color.
It is because of independent dominance.. The important point to note here that it is an exception to Mendel's law of dominance.
In Incomplete dominance both the dominant and recessive allele shows their effect and eventually the expressed offspring is the combination of dominant and recessive traits.
Lets take an example of mirabilis jalapa also known as 4 O' clock plant, in this red (dominant) and white (recessive) plants are crossed there's a blending of two alleles which produces a heterozygous pink flowered plant.
Cross between RR × rr :-
R R
r Rr Rr
r Rr Rr
All heterozygous pink flowered plants produced in F1 generation due to incomplete dominance. Snapdragon plant is also an important example of incomplete dominance.
