Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Behavioral Genetics and Its Designs

Behavioral Genetics and Its Designs

Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Causes of Social Behavior III: Biological and Environmental Influences

Causes of Social Behavior III: Biological and Environmental Influences

Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...

Area of Science:

Ecology
Epidemiology
Animal Behavior

Background:

Behavioral phenotypes can influence disease transmission dynamics.
Understanding these links is crucial for managing epizootic outbreaks in wildlife populations.

Purpose of the Study:

To evaluate the predictive value of behavioral phenotypes in larval amphibians for ranavirus transmission.
To identify specific behavioral traits associated with disease susceptibility and infectiousness.

Main Methods:

Experimental trials using larval amphibians exposed to ranavirus.
Characterization of behavioral phenotypes based on latency-to-food and swimming profiles.
Quantification of viral shedding rates and host-to-host transmission.

Main Results:

Behavioral phenotypes were significant predictors of ranavirus susceptibility and infectiousness.
Higher viral shedding rates correlated positively with transmission.
An inverse relationship was observed between contact rates and infection prevalence.

Conclusions:

Intrinsic behavioral traits and pathogen shedding influence ranavirus transmission.
Behavioral phenotypes can identify individuals likely to spread disease, aiding outbreak management.
This approach offers insights into disease dynamics affecting wildlife and potentially humans.
