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