By: Dr. Wayne Jarvis Link : journal@alpacagenetics.com This column, for the foreseeable future, will be devoted to providing the elementary building blocks of genetics to alpaca breeders who have never been taught about genetics. After having written two columns for AM over the last year on the more advanced topics of the genetics of animal [...]
By: Dr. Wayne Jarvis Entry #2 In the last entry in our Genetics Journal we discussed many of the introductory concepts of genetics including chromosome pairs; the genes located at specific locations called loci; the different versions of genes, called alleles, that can occur at one locus on each chromosome; the concepts of heterozygous, homozygous, [...]
By: Dr. Wayne Jarvis Entry #3 In our last entry in the Genetics Journal we discussed Gregor Mendel’s experiments with pea plants looking at the effects of a simple dominance effect on traits determined by one gene with two possible alleles. We also introduced the concept of a useful tool called a Punnett square. In [...]
By: Dr. Wayne Jarvis So far in the first three entries to the Genetics Journal we have reviewed the Basic Mendelian Principles for the inheritance of simply inherited traits including the concepts of genes, alleles, dominant and recessive traits, the Mendelian laws of Gene Segregation and Independent Assortment, genotypes, phenotypes, Punnett squares and simple dominance.
