Morphological differentiation of northern Morocco goat
Data from 183 animals raised in 61 flocks were collected to investigate the morphological characteristics of the Northern Morocco goat. Nine zoometric measures and seven combined indices were obtained. Three zones were defined based on geo-climatic characteristics and environmental influences: Mediterranean, Atlantic and Dual. The morphological variables showed the absence of sexual dimorphism...
متن کاملMorphological differentiation between two Moroccan goat breeds
The objective of this study was to identify morphological measurements that best distinguish Moroccan Barcha and Atlas goat breeds. Ten measurements (body weight - BW, body length - BL, heart girth - HG, withers height - WH, rump height - WH, back length - BAL, neck length - NL, head length - HL, ear length - EL, and ear width - EW) of 876 adult animals of both sexes (547 Barcha and 329 Atlas) ...
متن کاملEnvironmental component of morphological differentiation in birds.
Geographic character variation in birds is usually attributed to natural selection for phenotypes that reflect locally adapted genetic differences. However, experimental transplants of red-winged blackbird eggs between nests in northern and southern Florida, and from Colorado to Minnesota, show that in this species a significant proportion of the regional differences in nestling development is ...
متن کاملSex differentiation in goat fetus
Reproduction in domestic animals, as a major source of food and other products for human, has greatimportance and study of related subjects including sex differentiation and gonadogenesis during fetal life can solve many questions on normal development and various disorders of urogenital system. Since studies on sex differentiation in goat fetus are scarce, this study was performed. Twenty-five...
متن کاملTemporal analysis of Coxiella burnetii morphological differentiation.
Coxiella burnetii undergoes a poorly defined developmental cycle that generates morphologically distinct small-cell variants (SCV) and large-cell variants (LCV). We developed a model to study C. burnetii morphogenesis that uses Vero cells synchronously infected with homogeneous SCV (Nine Mile strain in phase II) harvested from aged infected cell cultures. A time course transmission electron mic...
