Final answer:
Dimorphic traits in biology include characteristics of fungi that can appear as either molds or yeasts depending on the temperature, as well as genetic traits in organisms that show dominant and recessive patterns of inheritance, according to Mendel's studies.
Step-by-step explanation:
Dimorphic traits are characteristics of certain fungi and other organisms that can exist in two distinct forms depending on environmental conditions. In the context of dimorphic fungi, these organisms exhibit the ability to morph from molds to yeast forms in response to temperature changes. Histoplasma capsulatum is a noteworthy example, as it grows as a mycelium at 25°C and as single, round yeast cells at 37°C, which correlates with the human body temperature. From the perspective of genetics, dimorphic traits can also refer to expressed and latent traits such as those identified by Mendel in plants. These include dominant and recessive traits, with dominant traits appearing unchanged in hybridization, while recessive traits may disappear but can reappear in future generations.
