In centric diatoms there is marked differentiation between nonmotile female gametes, which act as egg cells, and motile (typically uniflagellate) male gametes.
We also observed marked differentiation of the relative influence of intrinsic and effective hydrophobicity.
The annual AK-18 population showed marked differentiation from the others, and the two populations at PT-1 and CT-67, with higher genetic variation within populations, made a small cluster.
In the present study, there is marked differentiation between Central America and all four Amazonian population clusters.
The expression is particular high in tissues characterized by rapid proliferation and marked differentiation, and in tissues undergoing morphogenetic changes [ 9].
These studies contrast with the results obtained in the direct developer Acanthina monodon that exhibits marked differentiation between northern and southern Pacific Patagonia localities [ 39].
However, a finding that transposable element insertion sites showed marked differentiation between the forms indicated that reproductive isolation might affect a larger portion of the genome (Esnault et al. 2008).
Expression of genes marking differentiation towards each embryonic germ layer: ectoderm (NCAM, Nestin), mesoderm (SMA, Desmin) or endoderm (Troma-1) was then monitored.
Using a series of population genetic analyses, we show that Tibetan pig populations have marked genetic differentiations.
Due to differing selection pressures among habitats, the species has undergone marked adaptive differentiation and, thus, shows pronounced morphological, physiological, and behavioral differentiation across habitat types (Merilä 2013).
The use of plastid markers revealed marked genetic differentiation among populations.
