Question

Quizplus · Accepted Answer

Yani's eye color phenotype is brown, which is the observable trait or characteristic resulting from the interaction of his inherited genotype (genes for blue eyes from his mother and genes for brown eyes from his father) with environmental factors. Although Yani inherited the gene for blue eyes from his mother, the gene for brown eyes he inherited from his father is dominant over the gene for blue eyes, so he has brown eyes. Therefore, Yani's genotype is heterozygous (one dominant gene for brown eyes and one recessive gene for blue eyes), but his phenotype is brown eyes.
