Resemblance between two relatives - animal and plant breeding

Resemblance between two relatives – animal and plant breeding.

Lecture 4 Introduction to Quantitative Genetics II: Resemblance between relatives

Since an individual’s phenotype can be directly scored, the phenotypic variance VP can be estimated from measurements made directly on the random breeding population. In contrast, an individual’s breeding value cannot be observed directly, but rather must be inferred from the mean value of its offspring (or more generally using the phenotypic values of other known relatives). Thus estimates of ...

Investigation of Two Recessive Disorders in Breeder Bulls of Abbas Abad Animal Breeding Center

To prevent distribution of recessive alleles in dairy herds all bulls used for AI (Artificial Insemination) haveto be tested. In this study 26 blood and 4 semen samples were supplied from Iranian Holstein bulls used forAI. Genomic DNA was extracted from 100 μl of blood and 200 μl of semen. Samples were tested by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR...

Ecogeography and utility to plant breeding of the crop wild relatives of sunflower (Helianthus annuus L.)

Crop wild relatives (CWR) are a rich source of genetic diversity for crop improvement. Combining ecogeographic and phylogenetic techniques can inform both conservation and breeding. Geographic occurrence, bioclimatic, and biophysical data were used to predict species distributions, range overlap and niche occupancy in 36 taxa closely related to sunflower (Helianthus annuus L.). Taxa lacking com...
