He was responsible for the development of a whole genome cattle-hamster radiation hybrid (RH) panel. This work fueled a new thrust in cattle genomics and comparative gene mapping. RH mapping is an effective tool for building ordered maps of conserved sequences, derived from genes, thus integrating linkage and physical maps of mammalian chromosomes.
Molecular breeding is the application of molecular biology tools, often in plant breeding [1] [2] and animal breeding. [3] [4] In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted ...
She began her five-year term in the role in May 2023. [1] She is also a professor and Canada Research Chair in Livestock Genomics at Ontario Agricultural College at the University of Guelph. [2] Dr. Christine Baes is a prominent figure in animal science, particularly in the fields of quantitative genetics, genomics, and animal breeding.
Diagram illustrating the development process of avian flu vaccine by reverse genetics techniques. Reverse genetics is a method in molecular genetics that is used to help understand the function(s) of a gene by analysing the phenotypic effects caused by genetically engineering specific nucleic acid sequences within the gene.
Comparative genomics analyses of human and chimpanzee genomes have revealed that CNVs may play a greater role in evolutionary change compared to single nucleotide changes. Research indicates that CNVs affect more nucleotides than individual base-pair changes, with about 2.7% of the genome affected by CNVs compared to 1.2% by SNPs.
The size of the bovine genome is 2.7 Gb (2.7 billion base pairs). [4] It contains approximately 35,092 [4] genes of which 14,000 are common to all mammalian species. Bovines share 80 percent of their genes with humans; cows are less similar to humans than rodents (humans and rodents belong to the clade of Supraprimates) and dogs (humans and dogs belong to the clade of Boreoeutheria).
Ab Initio gene prediction is an intrinsic method based on gene content and signal detection. Because of the inherent expense and difficulty in obtaining extrinsic evidence for many genes, it is also necessary to resort to ab initio gene finding, in which the genomic DNA sequence alone is systematically searched for certain tell-tale signs of protein-coding genes.
A metaphase cell positive for the BCR/ABL rearrangement using FISH. Cytogenetics is essentially a branch of genetics, but is also a part of cell biology/cytology (a subdivision of human anatomy), that is concerned with how the chromosomes relate to cell behaviour, particularly to their behaviour during mitosis and meiosis.
