Short communication: Genetic variation in estrus activity traits.
Genetic variation in estrus traits derived from hourly measurements by electronic activity tags was studied in an experimental herd of Holstein (n = 211), Jersey (n = 126), and Red Dane (n = 178) cows. Both virgin heifers (n = 132) and lactating cows in the first 4 parities (n = 895 cow parities) were used, giving a total of 3,284 high-activity episodes indicating estrus. The first estrus after...
متن کاملGenetic Variation within Iranian Iris Species Using Morphological Traits
Iris belongs toIridaceae family and it is monocotyledon. Iris is one of the important ornamental and medicinal plants. 34 iris genotypes (14 species) collected from different provinces of Iran were planted at National Institute of Ornamental Plants (NIOP) Iran. All of the species evaluated for 15 quantitative traits and 30 qualitative traits. Results showed that the highest positive correlation...

In the present investigation attempts were made to estimate genetic parameters for yield and its components in 315 genotypes of cocoyam collected from thirteen aroid growing districts. Plant height, petiole length, petiole breadth, leaf number, leaf length, leaf breadth, LAI, Inflorescence length, peduncle length, spathe length, spathe breadth, corm length, corm breadth, cormel number, cormel l...
متن کاملCommon genetic variation and human traits.
T human genome has been cracked wide open in recent years and is spilling many of its secrets. More than 100 genome wide association studies have been conducted for scores of hu man diseases, identifying hun dreds of polymorphisms that are widely seen to influence disease risk. After many years in which the study of complex human traits was mired in false claims and methodologic inconsistenc...
متن کاملGenetic Variation of Informative Short Tandem Repeat (STR) Loci in an Iranian Population
In the present study, genotyping of six short tandem repeat (STR) loci including CSF1PO, D16S539, F13A01, F13B, LPL and HPRTB was performed on genomic DNA from 127 unrelated individuals from the Iranian province of Isfahan. The results indicated that the allele and genotype distributions were in accordance with Hardy-Weinberg expectations. The observed heterozygosity (Ho), expected heterozygosi...
