The goal of many captive breeding programs is to retain the genetic/genomic diversity (GD) present in the captive founding population until such time that reintroduction of captive populations to wild habitats can occur [1, 2].Retaining GD in a small, closed captive population is important as decreased GD across the genome often results in decreased fitness [3, 4].Request PDF | Inbreeding depression for producer-recorded udder, metabolic, and reproductive diseases in US dairy cattle | This study leveraged a growing data set of producer-recorded phenotypes ...THIS is the "world's most inbred family" with four generations of incest -including at least 14 kids with parents all related to each other.

Before we discuss inbreeding depression, let us first discuss estimation of inbreeding, usually measured through Wright's inbreeding coefficient F [22]. Traditionally, the use of detailed pedigree data to estimate inbreeding, the probability of identity by descent (IBD) of the two alleles in a diploid individual from a common ancestor, has been ...Inbreeding causes the number of direct ancestors in a pedigree to differ from 2 t (where t is the number of generations in the past). For example, the progeny of first cousin matings have six, rather than eight, great-grandparents. As inbreeding affects the number of ancestors in a pedigree, it results in modified organismal coalescence times.Scientists have proven inbreeding brought about severe facial deformations and collapsed of one of Europe’s most powerful historical dynasties.. The royal European Habsburg family sat on the throne of the Holy Roman Empire from 1438–1740 AD and scientists have now proven that while carefully arranged intermarriage helped build their vast empire, it also led to their extinction.

In the United States, selective chicken breeding began accelerating in the 1960s. In the 1950s, an average chicken used for their meat—known in the industry as a "broiler" chicken—weighed about two pounds at 56 days old. Today, after decades of selective breeding, an individual bird of the same breed and age weighs in at more than nine pounds.

Recently there have been increased reports of autism, yet the disease is not contagious. Since it is not catching, there must be other forces at work that somehow create or pass on the autistic symptoms. DNA reports show that deviations in the genetic code due to ancient inbreeding can follow a human line for generations. Studies show that inbreeding was widespread until a few hundred years ...

2. White tigers in captivity exist due to inbreeding. The white tiger is a result of a rare genetic mutation and the most efficient way to breed them is by using two tigers who have the recessive genes needed to produce offspring with a white coat. In captive breeding facilities these two individuals are often related, making inbreeding common.

An inbreeding study of current data could show more dramatic effects of inbreeding on CD and SB than we report here.Previous economic analyses of inbreeding depression suggested lifetime losses per cow in the order of tens of US dollars per 1% increase in inbreeding [10, 12, 39]. These analyses confirm that, by affecting various traits, inbreeding depression reduces net income. Combined with the importance of conserving genetic diversity for future ...
