Question : How was it concluded that genes are located on chromosomes ? |
| Answer» Solution :Morgan CONFIRMED MENDELIAN laws of inheritance and the hypothesis that GENES are located on chromosomes. Morgan had discovered that eye colour in Drosophila expressed a sex-linked trait. All first-generation offspring of a mutant whiteeyed male and a normal red-eyed female would have red EYES because every chromosome pair would contain at least ONE copy of the X chromosome with the dominant trait. | |
