Ch 15. 1 - 15. 3: chromosme theroy of inherience, genes have specific loci on chromosomes, chromosomes undergo segregation and independent assortment, thomas morgan, early 20th century experimental embryologist, prior to morgan: 1860s-1900s- cytologist said chromosomes behave like mendel"s heritable factors : morgan originally skeptically of mendel"s work chromosomes theory fit what was known about mendel"s heritable factor . 1st experimental support on chromosomes on genetic importance of morgan"s work: drosophila melanogaster. F1: all offspring have red eyes: red eyes dominant. Unique inherence patterns for genes on sex chromosomes. Strong support for chromosome theory of inheritance: sex chromosmes, autosomes: any chromosome other than sex chromo, homomorphic (homologs the same shape, most homo, sex chromosomes (cont, most of the time, specific location of a gene doesn"t matter, properties. X linked genes controlled by genes on x chromo: x- linked genes, may required genes.
