概括
评估了末期杂交羊的羊毛质量. 虽然杂交的羊毛产量相似,但它们的质量,特别是纤维直径,各不相同,Merino x Dormer产生的羊毛最粗.
科学领域:
- 动物科学动物科学
- 织科学 织科学
- 羊的养殖 羊的养殖
背景情况:
- 关于末期杂交羊的羊毛质量的数据有限.
- 了解交叉的羊毛特征对于优化生产和产品开发至关重要.
- 梅里诺和多恩梅里诺品种是成熟的羊毛生产商,作为比较的有价值的水线.
研究的目的:
- 为了评估和比较四个杂交羊系的羊毛质量特征.
- 评估不同种子 (多尔默,法兰西岛) 对羊毛特性的影响.
- 为了将杂交羊毛的质量与纯种梅里诺和多恩梅里诺大线进行比较.
主要方法:
- 通过将梅里诺和多恩梅里诺水母与多尔默或伊尔德法国水母交配,产生了四个杂交系.
- 纯种美利诺犬和多恩美利诺犬的品种被保留作为对照.
- 来自一岁羊的羊毛样本分析了羊毛的重量,产量,纤维直径和舒适度.
主要成果:
- 没有观察到性别或基因型对干净毛皮重量或干净产量百分比的显著影响.
- 在基因型之间发现了纤维直径的显著差异;纯种梅里诺羊毛最细 (18.26微米),而梅里诺x多默羊毛最粗 (26.01微米).

01:08Cloning of Dolly the Sheep
3.7K
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...

01:39Epistasis
46.8K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

02:27Background and Environment Affect Phenotype
6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:33Pleiotropy
40.5K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
