What is an inbred strain of mice?
What is an inbred strain of mice?
Inbred mouse strains are defined as colonies produced by a minimum of 20 generations of brother-sister mating, traceable to a single founding pair.
Which would be an advantage of using inbred strains of mice?
1. Economical – Inbred mice are considerably less expensive than mutant humanized models. 2. Fully developed immune systems – Inbred mice are immunocompetent, and, thus, allow for the study of infectious diseases and the compounds designed to treat them within the dynamics of fully functional immune systems.
How does inbreeding affect mice?
Mice have been inbred to reduce genetic variance for over a 100 years, and each generation of inbreeding is expected to lead to a decrease in heterozygosity (Wright 1921; Silver 1995).
What are the most common strains of mice used in research?
The most cited mouse strains are C57BL/6, BALB/c, CD-1, SCID, and A/J (Table 4). Only CD-1 is an outbred strain. Below we briefly discuss each of these strains. hybridoma and monoclonal antibody production, research models for cancer therapy and immunology.
How many inbred strains of mice are there?
Each inbred strain has its own unique pattern of behavior, growth patterns, reproductive performance, spontaneous disease (including tumors), and response to xenobiotics. Differences between strains are an indication that the observed character is under genetic control. Currently, there are over 200 inbred rat strains.
What breeding scheme is generally recommended for inbred strains of mice?
1. Trio breeding groups are best suited for the propagation of inbred, transgenic, or other strains of mice which generate small numbers of pups or are difficult to breed. Crosses that produce larger litters are best propagated by a pair (defined as one male and one female) breeding strategy.
Are white mice rare?
An albino mouse is one of the most common rodents found in lab experiments. But is quite an uncommon pet.

Are blue eyes a mutation caused by incest?
All the blue-eyed people in the world have a single, common ancestor from 6,000-10,000 years ago who had a genetic mutation for eye colour. Given blue eyes is a recessive gene, a single ancestor also requires incest among his/her kids doesn’t it? No. Gene can be passed on for generations without showing.
