Acertain flower is a pink color that breeders have determined is a single gene recessive trait. what must be true about the gene to determine flower color? a. it has 2 dominant alleles. b. it has at least 1 dominant allele. c. it has only 1 recessive allele. d. it has 2 recessive alleles.

If a trait is recessive, the only way for it to show as the phenotype is if the genotype has 2 recessive alleles (homozygous recessive).

If a trait is dominant, the allele would take over in the presence of a recessive one (heterozygous).

So, if pink is recessive the plant must have 2 of the same recessive alleles to make a pink flower.

Hope that helps!
