Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles.
What is dimorphism anthropology?
Sexual dimorphism refers to differences in size and shape between females and males of the same species. Sexual dimorphism has an important place in biological anthropology.
What type of selection is responsible for dimorphism?
sexual selection
Strong sexual selection typically results in sexually dimorphic traits that are exaggerated, or more elaborate, in the sex with highest reproductive variance (Figure 1).
What is dimorphism in biology?
Dimorphism. Having two different distinct forms of individuals within the same species or two different distinct forms of parts within the same organism.
What dimorphism means?
Definition of dimorphism : the condition or property of being dimorphic or dimorphous: such as. a : the existence of two different forms (as of color or size) of a species especially in the same population sexual dimorphism. b : the existence of a part (such as leaves of a plant) in two different forms.
What is dimorphism in microbiology?
Dimorphism is defined as the ability of a fungus to generate free-living vegetative cell types that are either yeast or hyphal (Fig. Simple cartoons of the environmental and host forms of each fungal species are shown. In the environmental hyphal form of these organisms, oval swellings depict vegetative conidia.
Why is dimorphic important?
The ability of pathogenic fungi to switch between a multicellular hyphal and unicellular yeast growth form is a tightly regulated process known as dimorphic switching. Dimorphic switching requires the fungus to sense and respond to the host environment and is essential for pathogenicity.
What is chloroplast dimorphism?
Dimorphic chloroplasts are the chloroplasts which are concentrated into two types of cells having different size and structure. The dimorphic chloroplast is present in C4 plants because of the presence of special leaf anatomy called Kranz anatomy.
What is thermal dimorphism?
The thermally dimorphic fungi are a unique group of fungi within the Ascomycota phylum that respond to shifts in temperature by converting between hyphae (22–25°C) and yeast (37°C). This morphologic switch, known as the phase transition, defines the biology and lifestyle of these fungi.
What is the Kranz anatomy?
Kranz anatomy is a specialized structure in C4 Plants where the mesophyll cells are clustered around the bundle-sheath cells in a ring-like fashion. The number of chloroplasts in the bundle-sheath cells is more than that in the mesophyll cells. This is found in C4 grasses such as maize and a few dicots.
