Understanding and estimating inbreeding is essential for managing threatened and endangered wildlife populations. However, determination of inbreeding rates in natural populations is confounded by incomplete parentage information. We present an approach for quantifying inbreeding rates for populations with incomplete parentage information. The approach exploits knowledge of pedigree configurations1. Introduction.

The white tiger is a result of a genetic mutation and the most efficient way to breed them is by using two tigers who have the recessive alleles needed to produce offspring with a white coat. In captive breeding facilities these two individuals are often related, making inbreeding common.2.1. Overview. We evaluated genetic variation among L. verrilli colonies and their offspring in sites with differing degrees of spatial isolation to make inferences about philopatric local retention, relatedness, and the magnitude of inbreeding. We employed "mixed mating" progeny arrays, a tool primarily developed to estimate self‐fertilization in seed plants (Ritland, 2002), to quantify ...

This genetic condition, also called prognathism, is connected to noble families. The Spanish House of Habsburg came to power during the mid-1400s and remained there until the mid-1700s, but during that time, there was quite a bit of inbreeding.Rather than marrying outside the family, the Habsburgs arranged close marriages to protect their interests.Full text.

If close relatives of such a dog are used for breeding, they should be mated to dogs from bloodlines with low or no occurrence of the same disease. 2. The breeding program should not exclude more than 50% of the breed; the breeding stock should be selected from the best half of the population. 3.

Abstract. Inbreeding depression (reduced fitness of individuals with related parents) has long been a major focus of ecology, evolution, and conservation biology. Despite decades of research, we still have a limited understanding of the strength, underlying genetic mechanisms, and demographic consequences of inbreeding depression in the wild.

A much-acclaimed ‘injection of fresh blood’ occurred in 1947, when a wild-caught mare, Orlica 3, was brought to Askania Nova in Ukraine. A stallion, Robert, was imported from Munich to be her partner, and breeding of Przewalski horses again held some promise. In the 1950s and 60s, breeding took off.Introduction. Inbreeding is the main consequence of mating individuals that are related, through common ancestry, to a degree that exceeds that of two individuals from the same population extracted at random (Kardos et al., 2016).Minimizing inbreeding is an aspect of paramount importance in cattle breeding to avoid the phenotypic expression of detrimental alleles in the offspring as well as to ...Define inbreeding. mating of individuals that are relatives.

Inbreeding is common in flowering plants (Barrett & Eckert, 1990).Because inbreeding reduces heterozygosity, thereby exposing deleterious recessive alleles to selection while decreasing the contribution of over-dominance to fitness, most species show a significant loss of fitness with inbreeding (Charlesworth & Charlesworth, 1987; Husband & Schemske, 1996; Crnokrak & Barrett, 2002).
