Variation in genetic composition in backcrossing programs
Article Abstract:
The results obtained from a formula for the variance in the contribution to the total genome from the non-recurrent parent over successive generations in a backcrossing program in the case of mammals show that changes in the distribution of chromosome lengths do not have a significant impact. The results also include values for an approximate upper bound to the contribution from the noncurrent stock. More precise values can be obtained only by the derivation of the distribution utilizing the methods of stam.

Genome size of bisexual and unisexual Poeciliopsis
Article Abstract:
Genome size of bisexual and unisexual fishes in Poeciliopsis was investigated by flow cytometry. Poeciliopsis monacha and P. lucida were observed to have genome sizes of 1.45-1.47 pg DNA and 1.37 pg DNA, respectively. P. monacha-lucida had intermediate genome size of its sexual progenitors. No change in genome size was observed from the time of parental species hybridization to production.

Divergent origins and concerted expansion of two segmental duplications on chromosome 16
Article Abstract:
A model of rapid expansion and evolutionary turnover among the genomes of man and the great apes is supported by the evolutionary history of the two chromosome duplications. The data suggest that the two copies of genomic sequence are brought together during the chimpanzee/human divergence and are subsequently duplicated as a larger cassette within the human lineage.
