learn the difference between genes and alleles, and how they are inherited and expressed. Genes are segments of dna that code for specific traits, while alleles are alternative. Different forms of the same gene. A variation of a gene's nucleotide sequence (an alternative form of a gene). An organism's genetic makeup or allele. an allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These dna codings determine distinct traits that can. if the alleles for a characteristic in a homologous pair are different; The characteristic depends on which allele is dominant and which allele is recessive; 3 days ago · learn the definition and examples of alleles, the different forms of a gene that can vary in sequence and function. Test your knowledge with flashcards and quizzes on inheritance, genotype, phenotype, and more. there are multiple alleles for the abo blood group. Why are only two of these alleles present in any one individual?
