WebMar 9, 2024 · Gene vs allele. Genes are chunks of DNA that contribute to particular traits or functions by coding for proteins that influence physiology. Alleles are different versions of a gene, which vary according to the nucleotide base present at a particular genome location. An individual's combination of alleles is known as their genotype. WebDec 28, 2024 · Genetic traits are characteristics that are encoded in DNA. Some genetic traits, like dimples, have a simple inheritance pattern like the traits that Gregor Mendel studied in pea plants.
