What are dimorphic traits?

Sexual dimorphism is the condition where the sexes of the same species exhibit different characteristics, particularly characteristics not directly involved in reproduction. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits.

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 are dimorphic branches?

Branch dimorphism is initiated after 1 to 2 years of growth at which time the apical meristem of the orthotropic shoot aborts and a pseudowhorl of plagiotropic branches is initiated from axillary positions in the shoot tip. The apical meristem of this shoot eventually aborts and another pseudo- whorl is formed.
