Polygenic Traits01:18

Polygenic Traits

67.5K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Genome-wide Association Studies-GWAS

14.9K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Genomic Imprinting and Inheritance

35.9K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Behavioral Genetics and Its Designs

736
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Area of Science:

  • Animal Genetics
  • Dairy Science
  • Reproductive Biology

Background:

  • Twinning in dairy cattle negatively impacts animal welfare and economic sustainability.
  • Genetic selection for reducing twinning rates has been proposed but not implemented.

Purpose of the Study:

  • Describe a genetic evaluation for twinning in Holstein cattle.
  • Demonstrate the efficacy of genomic predictions for twin pregnancies.
  • Propose strategies to reduce twin pregnancies using genetic information.

Main Methods:

  • Defined twin pregnancies (TWIN) as a binary trait (0,1).
  • Analyzed TWIN using a threshold animal model with data from commercial dairies.
  • Compared genomic predictions to on-farm twin records.

Main Results:

  • Heritability for twin pregnancies was 0.088.
  • Genomic predicted transmitting abilities (gPTAs) ranged from -7.45 to 20.79.
  • Genetic correlations between TWIN and other traits were low, indicating no negative impact on other selection goals.

Conclusions:

  • Genomic predictions effectively identify cows with high or low likelihood of twin pregnancies.
  • Integrating this prediction into multitrait selection indices offers a tool for producers.
  • Combined with management practices, this can proactively reduce twinning incidence in dairy operations.
