Animal anatomy, physiology and genetics, part 2: animal genetics
Code: G280FD
Teacher:  Pietro Parma
Year: 
Term: 
CFU: 
CFU subdivision: Lectures: 3
Other: 1
Basic aims:  The course supplies basics of vertebrate biology, and an
introduction to the structural organization and
physiological mechanisms of domestic animals. It has the
aim to provide basic acquaintance and specific knowledge,
necessary to the studies of animal nutrition and animal
production. The course provides also knowledge about the
basic principles of genetics and their applications to farm
animal species.
Acquired skills:  Basic acquaintance and specific knowledge of structure
and function of domestic animals, with emphasis on
physiological systems of importance to animal nutrition
and animal production. Ability of comparing the anatomy
and the physiology of different mammals. Skills in
biological and technical language necessary to describe
physiological processes. Knowledge of the hereditary
transmission of qualitative and quantitative traits in farm
animal species.
Course contents:  Program of unit 2: animal genetic

Knowledge of the hereditary transmission of qualitative
and quantitative traits in farm animal species .
Program:  Program of unit 2: animal genetic

Basic issues: DNA and molecular structure of
chromosomes. Flow of genetic
information: DNA replication, transcription and RNA
maturation, translation and genetic code.
Mendelian genetics: Mendel’s laws. Mendelian traits in
farm animals. Tests of genetic hypotheses. Allelic
variability: incomplete dominance and codominance,
multiple alleles. Penetrance and expressivity. Genetic
interaction. Epistasis and pleiotropy.
Chromosomal basis of mendelism. Chromosomes,
chromosomal theory of genetic transmission, karyotype
and chromosomal abnormalities. Gene and sex. Sexual
determination. Association, recombination and crossing
over. Evolution of gene definition.
Introduction to population genetics: gene and genotypic
frequencies. Hardy-Weinberg law. Forces that causes
change in gene and genotypic frequencies: nonrandom
mating, migration, selection and genetic drift.
Relationship and inbreeding: heterosis and inbreeding
depression.
Introduction to quantitative traits: QTL and polygenic
model. Statistical description of quantitative traits:
normal distribution, central indexes and measures of
variation . Heritability.
