Excerpt from The Effects of Inbreeding and Crossbreeding on Guinea Pigs, Vol. 3: Crosses Between Highly Inbred FamiliesOf 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.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
