Document Summary
Be able to identify allele and how the alleles behavior is correlated with chromosomal pairs. Identify x linked genes how they differ from autosomal genes, and how they express. Compare and contrast linked, sex linked, and independent genes. To be homozygous recessive both parents must pass on the allele b so, =1/4 to determine probability we multiply the probability of one event by the probability of the other event. this is only in the case of an and situation. ~1902: scientists began to develop the chromosome theory of inheritance : genes have specific loci on chromosomes, chromosomes undergo segregation and independent assortment. Evidence that chromosomes are the location of mendel"s heritable factors : morgan"s experimental organism. Morgan chose to study drosophila melanogaster a common species of fruit fly. A convenient organism for genetic studies: 100"s offspring, eggs every two weeks, four pairs of chromosomes. Traits studied in drosophila melanogaster: wild type phenotype for character most commonly observed in population ex.
