imagine you are studying the trait of a flower petal shape in a species of plant. petal shape is determied by a single gene with two alleles. you make a cross of the two plants with unknown genotypes, both with smooth petals, and get the following f1 offspirng phenotypes: 23 wrinkled and 77 smooth. what conclusions can you draw about the inheritance of this trait? in your answer, include the probable genotypes of each parent, and which allele is likely dominant.
