Since the gene for albinism is recessive, it only shows up in the phenotype of homozygous Chromosomes are composed primarily of DNA and protein. . a genotype consisting of two different alleles of a gene for a particular trait (Aa). There is a correlation between the amount of sunlight that children are exposed to. What role do genes play in development? How does your genotype contribute to your phenotype? Or more explicitly, how do genes work. An individual's genotype for that gene is the set of alleles it happens to possess.
