Answer :
All the plant are homozygous for flower color then flower color is dominant trait.
homozygous may be dominant or recessive, but the offspring here consist of all pink color indicating it to be dominant.
If the flower color is dominant, it means it has dominant allele.
Dominant allele always suppresses the recessive allele result in dominant phenotype expression.
But, when a homozygous and heterozygous is crossed we get 50% homozygous and 50% heterozygous, where 3 are dominnat and one is recessive. this is in the case of normal crossing where both homozygous and heterozygous parents are present.
with the results of offspring, one can denote that in parents the flower color is a dominant trait.
