classical genetics is the part of genetics that is solely about the method in which genetic traits are transmitted via the acts of reproduction. genetics is, generally, the study of genes, genetic variation, and heredity. the process by which characteristics are passed down from parents to their offspring is called heredity. in the sense of classical genetics, variation is known as the lack of resemblance in related individuals and can be categorized as discontinuous or continuous. genes are a fundamental part of dna that is aligned linearly on a eukaryotic chromosome. chemical information that is transported and encoded by each gene is referred to as a trait. many organisms possess two genes for each individual trait that is present within that particular individual. these paired genes that control the same trait is classified as an allele. in an individual, the allelic genes that are expressed can be either homozygous, meaning the same, or heterozygous, meaning different. many pairs of alleles have differing effects that are portrayed in an offspring's phenotype and genotype. the phenotype is a general term that defines an individual's visible, physical traits. the genotype of an offspring is known as its genetic makeup. the alleles of genes can either be dominant or recessive. a dominant allele needs only one copy to be expressed while a recessive allele needs two copies (homozygous) in a diploid organism to be expressed. dominant and recessive alleles help to determine the offspring’s genotypes, and therefore phenotypes.

genetic makeup has been found to impact skill learning and performance, and therefore plays a role in achieving expertise. using the pursuit rotor task, one study examined the effects of practice in identical and fraternal twins raised in separate homes. because identical twins share 100% of their genes while fraternal twins share 50%, the impact of genetic makeup on skill learning could be examined. the results of the pursuit rotor task test became more identical with practice over time for the identical twins, whereas the results for the fraternal twins became more disparate with practice. in other words, the performance of the skill by the identical twins became closer to 100% identical, while the fraternal twins' skill performance became less identical, suggesting the 50% difference in genetic makeup is responsible for the difference in skill performance. the study shows that more practice leads to a closer representation of a person's innate capability, also known as talent. therefore, some of the differences people show after extended practice increasingly reflects their genetics. the study also confirmed the idea that practice improves skill learning by showing that, in both the identical and fraternal groups, more practice aided in shedding ineffective tendencies in order to improve execution of a given skill. currently, the link between learning and genetics has been limited to simple task learning, while a link to more complex forms of learning, such as the learning of cognitive skills, has not been confirmed.
