Excerpt from The Effects of Inbreeding and Crossbreeding on Guinea Pigs, Vol. 3: Crosses Between Highly Inbred Families
Of the 17 inbred families still in existence in 1916, only 5 have been retained to the present. It seemed necessary to eliminate the others in order to make room for the crossbreeding experiments and to obtain sufficient numbers from these five. Families 2, 13, 32, 35; and 39 were the ones retained, partly because they occupied a large number Of pens, and partly because Of contrasting characteristics. Family 39, for example, had the least white in the coat, while Family 13 had the most. Family 32 had a peculiar intense golden agouti. Families 2 and 13 were at Opposite extremes in weight and also contrasted in size of litter.

The Effects of Inbreeding and Crossbreeding on Guinea Pigs, Vol. 3
Print-on-DemandAnbieter: Forgotten Books, London, Vereinigtes Königreich
Verkäuferbewertung 5 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book presents the results of the author's inbreeding experiments conducted on guinea pigs over multiple generations. The aim of these experiments was to assess the effects of continuous inbreeding. The study went on to examine the effects of subsequently crossing these inbred lines. Over several generations, inbred animals showed a decline in numerous fitness traits and characteristics, including percentage born alive, birth weight, and size of litter. The study then looked at whether crossing these inbred lines could restore some of these lost qualities and found that many were indeed partially restored, even in the first generation of crossing. This book is a valuable contribution to the field of genetics. By providing detailed explanations of the methodology and results of the experiments, the book allows readers to delve deeper into the concepts of inbreeding and crossbreeding and the effects they have on various characteristics. This research offers essential insights into the complex dynamics of genetics and the importance of genetic diversity in maintaining the health and vigor of populations.
