概括

遗传分析显示,法罗群岛的羊保持着古老的血统,历史进口的影响很小. 它们独特的遗传特征使它们在北大西洋短尾品种中处于边缘地位,这表明它们与当代品种有着遥远的关系.

科学领域:

动物遗传学动物遗传学
绵羊品种的进化是如何演变的
人口遗传学人口遗传学

背景情况:

法罗群岛绵羊的历史不清楚,有潜在的维京起源和维京前的痕迹.
历史记录显示,在1600年左右,羊几乎灭绝,随后从冰岛和周边岛屿进口.
北方法罗群岛绵羊与其他品种的遗传关系需要研究.

研究的目的:

研究北方法罗群岛绵羊与其他全球品种的遗传关系.
了解历史事件和进口对法罗群岛绵羊种群的遗传影响.

主要方法:

使用GeneSeek Genomic Profiler Ovine 50K芯片对来自三个岛屿的359只法罗群岛绵羊进行基因型定型.
费罗群岛羊的遗传数据与羊HapMap数据库和挪威白羊的比较.
基于原产岛屿的人口分层的分析.

主要成果:

法罗群岛绵羊的样本根据原产岛屿分为三个不同的群体,表明动物的移动有限.
法罗群岛绵羊在北大西洋短尾品种中处于边缘位置,冰岛绵羊和挪威斯帕尔是最接近的邻居.
遗传数据显示,与周围品种有着遥远的关系,与预期的历史影响相反.

结论:

1600年后从邻国进口的产品在法罗群岛绵羊的遗传数据中反映得很差.
法罗群岛的羊可能与1300年以前的种群有着不间断的遗传联系,可能是古挪威语和英国/爱尔兰动物的混合体.
遗传特征表明,随后北大西洋品种影响对其的影响有限.

Cloning of Dolly the Sheep

Cloning of Dolly the Sheep

The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Gene Flow

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Mutation, Gene Flow, and Genetic Drift

Mutation, Gene Flow, and Genetic Drift

In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Genetic Drift

Genetic Drift

Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.

Incomplete Dominance

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
