Basic Genetic Terms DNA is the set of instructions inside a cell that controls how an organism grows, develops, and functions. Genes are specific sections of DNA that control traits, and each gene can have different versions called alleles, with one inherited from each parent. Some alleles are dominant and show with just one copy, while others are recessive and require two copies. There are some that even show a blended effect through incomplete dominance. A fish’s genotype is its genetic makeup, while its phenotype is the visible traits those genes produce. #STEM #genetics #learn #bettabreeding #bettatok #fishtok #wickedbettas
