A trait is any gene-determined characteristic. Many traits are determined by the function of more than one gene. For example, a person's height is likely to be determined by many genes, including those affecting growth, appetite, muscle mass, and activity level. However, some traits are determined by the function of a single gene.
Genes from Mom & Dad Determine Your Traits
You are a diploid organism, meaning that you received one set of genes (called alleles) from your father and the other set of alleles from your mother.
The combination of these pairs of genes that you've inherited is called your genotype. Your genotype (DNA) determines the actual traits that you have (called the phenotype); such as eye color, nearsightedness, and whether or not you have dimples.
the inheritance of several genetic traits, including:
