| 1. | Alleles separate so that each gamete carries only one allele for each gene. |
| 2. | Genes for different traits can segregate independently during the formation of gametes. |
| 3. | Each allele in a pair segregates into a different sex chromosome. |
| 4. | Phenotypes segregate during gamete formation, leading to genetic variation. |
| I: | In Incomplete Dominance, F1 has a phenotype that does not resemble either of the two parents and is in between the two. |
| II: | In Co-Dominance, F1 has a phenotype that resembles both the parents. |
After analysis of results drawn from his experiments with pea plants, Mendel concluded:
| 1. | There is considerable genetic variation in garden peas. |
| 2. | Traits are inherited in discrete units, and are not the results of "blending." |
| 3. | Recessive genes occur more frequently in the F1 than do dominant ones. |
| 4. | Genes are composed of DNA. |
