Hello friends!!, in this publication i show an exercise in spanish to obtain genetic indicators
(Kinship and consaguinity) using the procedure ‘Proc Inbreed” in SAS. Te code can be downloaded in the attached document, for any question or comment, you can writenme a message.
Fraction of the loci with identical alleles by offspring in animal X.
If the inbreeding coefficient of animal X is 0.25, then it is 25% more homozygous than the breed average
Proportion of genes in common (identical by offspring) between individuals (relatives).
If the kinship coefficient between two animals is 0.25, then these have 25% more genes in common than another pair of individuals randomly taken from the population (breed)
Additive genetic relationship:
Measures the fraction of additive genetic effects that two animals have in common.
Indicates how reliable the records are in one of the relatives to predict the additive genetic value of the other relative
Additive Genetic Relationship=A(XY)
Look at the following family tree and answer the questions:
Answer the following questions
Genetics interactions (Inbreeding coefficient, Kinship coefficient, Additive genetic relationship and Consanguinity of progeny) between:
D11 y B11
X11 y C11
X11 y A11
Please run the code and watch the video
