When replication occurs, non-random segregation of sister chromatids ensures the fates of the daughter cells.
2.
Crossing over and random segregation during meiosis can result in the production of new alleles or new combinations of alleles.
3.
If cells are using a random segregation mechanism, then enough DNA label should remain in the cell to be detected.
4.
If a mutation occurs in CCOI in one chromosome of a mitochondrion, there may be random segregation of the chromosomes during mitochondrial fission to generate new mitochondria.
5.
Due to random segregation of the chromosomes during gametogenesis, each pregnancy will be subject to the same probabilities, regardless of the number of previously affected or unaffected offspring.
6.
Without specific evidence, the possibility of random segregation can never be excluded, and assumption of such randomness can indeed serve as a null-model . Many physiological and morphological differences between species can prevent hybridization.
7.
While it is possible to predict the genetic composition of a backcross " on average ", it is not possible to accurately predict the composition of a particular backcrossed individual, due to random segregation of chromosomes.
8.
Selection for specific phenotypes in dog breeding causes long-range linkage disequilibrium in their DNA . Certain areas of alleles have the tendency to separate less frequently than normal random segregation, which leads to long ranges of repeated DNA sequences.
