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...

Genomics

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Evolutionary Relationships through Genome Comparisons

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Area of Science:

Animal Genetics
Molecular Breeding
Livestock Improvement

Background:

Advancements in sequencing and molecular breeding enable accurate livestock breeding.
Genomic Selection (GS) offers superior accuracy and efficiency over traditional methods in animal breeding.
While widely used in cattle, GS research in sheep and goats remains limited.

Purpose of the Study:

To review the principles, methods, and factors influencing Genomic Selection (GS).
To elaborate on the current research progress, challenges, and future prospects of GS in sheep and goat breeding.
To provide references for implementing GS in ovine and caprine breeding programs.

Main Methods:

Review of existing literature on Genomic Selection (GS) principles and methodologies.
Analysis of influential factors affecting GS accuracy and efficiency.
Synthesis of research findings on GS application in livestock, with a focus on sheep and goats.

Main Results:

GS leverages genomic information for enhanced accuracy and efficiency in livestock breeding.
Significant progress has been made in applying GS to cattle, but less so for sheep and goats.
Key factors influencing GS performance include reference population size, marker density, and statistical models.

Conclusions:

Genomic Selection (GS) holds significant potential for improving sheep and goat breeding.
Further research is needed to overcome challenges and optimize GS implementation in these species.
This review provides a foundation for advancing GS in ovine and caprine genetic improvement.
