Final answer:
According to Mendelian genetics, if both parents have brown eyes, their offspring must have brown eyes.
Step-by-step explanation:
According to the Mendelian paradigm, the correct statement is (b) if both parents have brown eyes, their offspring must have brown eyes.
Mendelian genetics describes the inheritance of traits through the transmission of genes from parents to offspring. In this case, the gene for eye color is controlled by a dominant allele for brown eyes and a recessive allele for blue eyes. If both parents have brown eyes, they are likely homozygous for the brown eye allele, so all their offspring will inherit the brown eye allele and have brown eyes.
