Weblearn 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. A variation of a gene's nucleotide sequence (an alternative form of a gene).

An organism's genetic makeup or allele. Weban allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. Webif the alleles for a characteristic in a homologous pair are different; These dna codings determine distinct traits that can. Webthere are multiple alleles for the abo blood group. The characteristic depends on which allele is dominant and which allele is recessive; Test your knowledge with flashcards and quizzes on inheritance, genotype, phenotype, and more.

Webthere are multiple alleles for the abo blood group. The characteristic depends on which allele is dominant and which allele is recessive; Test your knowledge with flashcards and quizzes on inheritance, genotype, phenotype, and more. Why are only two of these alleles present in any one individual? Different forms of the same gene.
