| 1. | Mendel tested his hypothesis with a type of backcross called a testcross.
|
| 2. | Typically selection for either phenotype or genotype is performed prior to each backcross generation.
|
| 3. | It can also backcross with its parental species.
|
| 4. | Similarly, a F2 animal bred to an F1 animal creates a F2b backcross.
|
| 5. | Due to legislation restricting or preventing backcross to Boxers, introducing the gene into his lines.
|
| 6. | Overall, viability is reduced in these hybrids and they rarely backcross with their parent species.
|
| 7. | It also found that the sweet orange originated from a backcross hybrid between pummelo and mandarin orange.
|
| 8. | An F1 female can mate with a male Bactrian camel : the result is a B1 backcross Bactrian.
|
| 9. | To make sure each line has different resistant genes, each donor parent is used in a separate backcross program.
|
| 10. | This habitat is unfavorable to most other plants, but its allotetraploid descendants and their backcross hybrids may occur alongside it.
