Matching Pairs 9.1 Mendel LawsOnline version Relation of Mendel's laws of inheritance by Jorge Arizpe 1 Deoxyribonucleic acid, constituent of the genetic material. 2 Chromatide: Filament that constitutes the chromosomes, visible during the prophase and metaphase 3 Law of segregation: during meiosis the two alleles of each feature are separated. 4 They are the nucleotides of which the DNA is formed 5 Law of Dominance: A dominant gene determines the expression of a particular characteristic and prevents the expression of the recessive form of the gene. 6 Law of independent segregation: During the formation of gametes a random distribution of alleles occurs. Different alleles separate independently. 7 Chromosome: consists of hundreds of genes; humans have 23 pairs.
