Unlike any other country, Direct Genomic Values DGV have been published in Canada for genotyped animals as part of its genomic evaluation system. Ten years later, as of the December release, DGV will no longer be published or included in any outgoing data files associated with Canadian genetic evaluations. Some breeders have expressed their disagreement with this decision and misunderstanding continues to be propagated. This article provides further clarification regarding the decision to no longer publish DGV. The information in Figure 1 was regularly used as part of this educational campaign.

D ulation of similar animals which can interbreed A population of organisms which breed to produce fertile offspring A community of organisms which can interbreed. Link to this page:. ALL drawings should be done in pencil and labelled in blue or black ink. Draw diagrams or flow charts only when asked to do so. The diagrams in this question paper are NOT necessarily drawn to scale. Do NOT use graph paper. You must use a non-programmable calculator, protractor and a compass, where necessary. Write neatly and legibly.

A B C D A sex-linked recessive allele Non-disjunction of chromosomes during meiosis Two sperm cells fertilise one ovum Crossing-over during meiosis The chromosome complement of a human individual who inherits an X chromosome from the father, is.

Which ONE of the following is an example of artificial selection? When the levels of pollution increase, trees become black from the smoke. Which ONE of the following best describes what would happen to the number of dark moths when air pollution levels change? It can be concluded from the graph that during the cell cycle.. A B C D the interphase is the longest phase.

Their child has blood group O. What is the best explanation for this pattern of inheritance? A B C D The child has inherited the blood group directly from a grandparent. The parents are heterozygous for the blood group alleles. There has been a mutation in the blood group alleles. The result of profiling various DNA samples in a criminal investigation is shown below. Which conclusion about the crime could the DNA analyst draw?

Only suspect Y was involved. Suspects X and Y were both involved. Neither suspect X nor Y was involved. The table below shows some genotypes and phenotypes associated with a form of anaemia.

For two centuries, Jersey cattle were exported globally, adapting to varying climates and production systems, yet the founding population remained genetically isolated on the Island of Jersey. The Island of Jersey formally allowed the importation of pure Jersey cattle in This study characterized the genetic variation of 49 popular bulls from the Island of Jersey born from to and compared them to 47 non-Island Jersey bulls and cows, primarily from the United States In addition, 21 Guernsey cattle derived from the Island of Guernsey and 71 Holstein cattle served as reference populations for genetic comparison. When compared to Holstein and Guernsey, all Jersey clustered together by breed. The Jersey breed demonstrated increased inbreeding in comparison to Holstein or Guernsey with slightly higher estimates of inbreeding coefficients and identity-by-descent. The Island and United States Jersey have relatively similar, yet statistically different inbreeding estimates despite vastly different population sizes and gene flow. Signatures of selection within Island Jersey were identified using genome-wide homozygosity association and marker-based F ST that provided population informative single-nucleotide polymorphism SNPs.

It describes whether the reference population used for evaluation was composed of a single or multiple breeds. Breed base representation BBR was introduced in Most crossbreds have not been included in genomic evaluations because marker effects are computed separately within breeds. Edits that determine which animals are evaluated use a small set of breed-check markers see Breed conflict determination below. Using all markers allows each animal's ancestry to be estimated more precisely. Breed base representation estimates the percentage of DNA contributed to the animal by each of 5 evaluated breeds: Holstein, Jersey, Brown Swiss, Ayrshire, and Guernsey. These 5 new fields sum to with a minimum of 0 and a maximum of

Candidate Genes Associated with Fertility and Embryonic Development in Dairy Cattle

Cooperation has fueled genetic evaluations. By Chad Dechow. The author is an associate professor of dairy cattle genetics at Penn State University. I think our nation's budget mess has sharpened that focus to some extent and put routine genetic evaluations under the microscope of some USDA administrators. How much internal pressure exists to move genetic evaluations from USDA has been debated, but AIPL scientists are truly concerned that the government will force them to discontinue routine genetic evaluations.
