Genetic variation and evolutionary trade-offs for sexual and asexual reproductive modes in Allium vineale (Liliaceae).
Populations of Allium vineale commonly include individuals with very different allocation patterns to three modes of reproduction: sexual flowers, aerially produced asexual bulbils, and belowground asexual offsets. If selection is currently acting to maintain these different allocation patterns there must be a genetic basis for variation in allocation to these three reproductive modes. In addit...

متن کاملEnvironmental and Genetic Factors Affecting Early Growth Traits in Three Yemeni Indigenous Sheep Breeds
The data were collected from 1992 to 2009 in Burri, White Boni and Black Boni sheep maintained at the Regional Research Station in the Central Highlands of Yemen. Data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. The least square means for body weights (BW) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...
متن کاملDistance-dependent performance of asexual progeny in Allium vineale (Liliaceae).
Local adaptation within and among populations may have an impact on processes ranging from speciation to the evolution of mixed breeding systems and dispersal strategies. It is also one potential factor that could favor the production of asexual over sexual propagules. This field experiment tested whether asexually produced bulbils of Allium vineale demonstrate local adaptation to the parental ...
