Drosophila melanogaster - Sex linkage and inheritance of genes through cross breeding Abstract This experiment looks at the relationship between genes‚ generations of a population and if genes are carried from one generation to another. By studying Drosophila melanogaster‚ starting with a parent group we crossed a variety of flies and observe the characteristics of the F1 generation. We then concluded that sex-linked genes and autosomal genes could indeed be traced through from the parent generation

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
