In a monohybrid cross, a plant with red flowers and a plant with white flowers are crossed. Considering codominance, if the
generation is self-pollinated, what is the expected genotypic ratio in
?
Text Solution
Verified by ExpertsA
In codominance, both alleles express themselves independently when present together. Thus, heterozygote
shows both red and white colour simultaneously (not blending).
Parent plants: RR (red) × rr (white)
Gametes:
and
generation:
(red + white, codominant expression)
Selfing 
Genotypes in
Red only
Red + White (codominant expression)
r → White only
Genotypic ratio
