Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN Millions of mice and rats are bred for use in biomedical research each year. Worldwide, there are several large commercial breeding facilities that supply mice to research laboratories, but many facilities also choose to breed mice and rats in-house to reduce costs and increase research options. When breeding in the animal facility, researchers are able to manipulate the genetics of the...

Breeding Management in Rodent Studies

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Breeding management supports the 3Rs by minimizing unnecessary animal production and ensuring that only the number of animals required for a study is generated. Effective breeding strategies help reduce surplus animals and...

Zebrafish Breeding and Embryo Handling

2023
Zebrafish (Danio rerio) are an important model organism that is particularly valuable for research in developmental biology. Zebrafish are extremely fertile and can produce hundreds of progeny per week, so it is relatively easy to collect a large number of embryos for high sample numbers. Furthermore, zebrafish undergo rapid development and embryos are transparent, allowing for easy visualization of developmental processes. This video covers the steps required for the collection of newly...

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food. As humans' understanding of genetics advanced, improved crop varieties could be achieved more quickly. Artificial selection could be more directed, and crop varieties enhanced for favorable traits more quickly to produce better, more robust, or more palatable plants.
FAQs
Inheritance influences which traits offspring may receive from their parents, including physical, behavioral, and working characteristics. Because genetic variation means parents do not produce genetically identical outcomes in every offspring, selection cannot be reduced to appearance alone. Applying heredity principles helps breeders assess how parental choices may shape traits and supports more informed decisions about compatibility and health.
Genetic variation provides the differences on which selection acts. In a breeding program, it helps explain why offspring can show a combination of parental characteristics rather than a uniform result. Evaluating variation alongside desired traits also connects individual breeding goals with population diversity, a central biological concern when studying how selection influences domestic dog populations.
Mating must coincide with the female’s fertile period for sperm to encounter an available egg. After sperm fertilization, the resulting embryo develops during gestation in the uterus. This sequence connects reproductive timing, gamete function, embryonic development, and reproductive anatomy, while showing why understanding prenatal care is relevant to successful reproductive planning.
Before mating, breeders need to evaluate whether the parents are compatible, coordinate reproduction with the female’s fertile period, and consider inherited traits. These decisions combine reproductive biology with genetics: timing addresses the opportunity for fertilization, while parent selection influences expected characteristics and possible disorder transmission. The result is a planned reproductive workflow rather than an isolated mating event.
Knowledge of heredity can guide breeding choices intended to reduce the transmission of inherited disorders. By considering the traits and genetic background associated with potential parents, breeders can make more informed selections instead of focusing only on desired physical or working characteristics. This illustrates how genetic principles can support both trait selection and canine health objectives.
Dog breeding provides a practical context for examining artificial selection, in which human decisions influence which physical, behavioral, or working traits are favored. It also links heredity with population diversity and health, allowing biology students and researchers to consider how reproductive choices affect canine populations. The topic therefore connects individual breeding decisions with broader genetic and population-level outcomes.
