The phenotype of parents could be PpSs and ppss ie purple sweet or yellow and starchy
The genotype of the parents could be PpSs, ppss and PpSs
Explanation:
In corn kennel purple is dominant to yellow
sweet is dominant to starchy
Purple PP, Yellow pp
Sweet SS, starchy ss
Since the organism obtained have all 4 traits, it is concluded that genotype of parent is heterozygous.
From the punnet square,
PS Ps pS ps
PS PPSS PPSs PpSS ppss
Ps PPSs PPss PPSs Ppss
pS PpSS PpSs ppSS ppss
ps PpSs Ppss ppSS ppss
genotype ratio is 4:1:1:2
phenotype ratio is 8:3:3:2
The phenotypic ratio observed shows near similarity to experimental observation.
