Transgenic Mouse

Transgenic Mouse. In transgenic mice expressing this gene, toxicity entails transport of the protein to the nucleus, where it is sequestered into ubiquitinated aggregates that may be a cellular pathway for turnover of abnormal proteins.

Even for congenic lines at the same backcross generation, the length of this segment can vary greatly because of the inherently random distribution of crossover sites. Nevertheless, the expected average length of the differential chromosomal segment in centimorgans can also be calculated as [200 (1 - 2 -N )/N] where N is the generation number.

PCB3063 Chapter 23 You''ll Remember | Quizlet

To determine the number of genes involved in tail length, you first need to identify the number of phenotypic classes. Because the F2 generation contains 7 distinct tail lengths, that means that there are 7 different phenotypic classes. Recall that the number of phenotypic classes is equal to 2n + 1, wherein n is the number of genes. Thus, 2n ...
