1. If these characteristics are genetically determined, positive Assortative mating may increase homozygosity in the population.

2. 9q34, and 11p11.2–q12.1) were excluded in the Consanguineous families by either haplotype analysis for homozygosity via micro-satellite markers or by direct sequencing

3. In this family study one discrepancy, at first assumed to be a mother/child incompatibility (opposite homozygosity) proved to be due to a silent gene (amorph), GPT0.

4. Four animals were examined from this population and all possessed an identical 2n = 21 karyotype characterized by homozygosity for a derived acrocentric chromosome 3 (3a) and heterozygosity for a 9–10 fusion.
