Document Summary
Today we know that genes gregor mendel"s hereditary factors are lo. A century ago, the relationship of genes and chromosomes was not so ob. Many biologists were skeptical about mendel"s laws of segregation and in mounted that they had a physical basis in the behavior of chromosomes. Concept 15. 1 mendelian inheritance has its physical basis in. Around 1900, cytologists and geneticists began to see parallels between behavior of mendel"s factors. Using improved microscopy techniques, cytologists worked out the p. Chromosomes and genes are both present in pairs in diploid cells. Homologous chromosomes separate and alleles segregate during me. Fertilization restores the paired condition for both chromosomes and. Around 1902, walter sutton, theodor boveri, and others noted these para began to take form: The behavior of homologous chromosomes during meiosis can account f genetic locus to different gametes. The behavior of nonhomologous chromosomes can account for the indep genes located on different chromosomes. Morgan traced a gene to a specific chromosome.
