Which of the statements corroborates (confirms) known information about TYRP1 alleles in Solomon Islanders? The Solomon Islanders with a genotype "T/T" are unaffected homozygotes for the condition. The Solomon Islanders with the genotype "T/C" or "C/C" have blond hair. Among the Solomon Islanders, a gene called tyrosinase-related protein 1 (TYRP1) in chromosome 99 plays a role in melanin production and is responsible for blond hair among the islanders.
