The SAT Subject Test in Biology assesses students' knowledge and understanding of biological concepts and processes.
Genetics is the study of how traits are passed from parents to offspring. DNA, found in chromosomes, contains genes—the instructions for building proteins.
Gregor Mendel discovered that traits are inherited in predictable patterns. Terms like dominant, recessive, genotype, and phenotype come into play.
Genetics explains family resemblances, inherited diseases, and even variations in plants and animals.
Scientists use genetics to develop better crops, understand genetic disorders, and create DNA fingerprinting techniques.
Brown eyes are often dominant over blue eyes.
Cystic fibrosis is caused by a recessive gene mutation.
Genetics explains how traits and characteristics are inherited from one generation to the next.
