Chapter 15 The chromosomal basis of inheritance Key ideas: 1) Mendelian Inheritance has its physical basis in the behavior of chromosomes during sexual life-cycle. 2) Morgan traced a gene to a specific chromosome. 3) Linked genes tend to be inherited together because they are located on the same gene. 4) Independent assortment of chromosomes and crossing over produce genetic recombinants. 5) Geneticists use recombination data to map a chromosome’s genetic locus. 1900 Biology finally
