Which of the following was not a reason why Drosophila melanogaster were found very suitable for genetic studies?
| 1. | They could be grown on simple synthetic medium in the laboratory. |
| 2. | They complete their life cycle in about two weeks. |
| 3. | A single mating produce a very limited number of progeny flies, generally one. |
| 4. | There was a clear differentiation of the sexes – the male and female flies are easily distinguishable |

The chromosomal theory of inheritance suggests that:
| 1. | Genes are located on chromosomes and segregate during meiosis. |
| 2. | Genes blend together to form new traits. |
| 3. | Alleles are inherited randomly without connection to chromosomes. |
| 4. | Traits are passed down without involvement of genetic material. |
