Plant Breeding and Biotechnology

21.5K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Distributions to Estimate Population Parameter

5.1K
The accurate values of population parameters such as population proportion, population mean, and population standard deviation (or variance) are usually unknown. These are fixed values that can only be estimated from the data collected from the samples. The estimates of each of these parameters are sample proportion, the sample mean, and sample standard deviation (or variance). To obtain the values of these sample statistics, data are required that have particular distribution and central...

Polygenic Traits

69.0K
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...

Trait and State Self-Esteem

11.5K
The term self-esteem is often used generically, to refer to how people feel about themselves. However, according to research, there are three distinct constructs that should not be used interchangeably (Brown & Marshall, 2006).

Traits and States

542
Personality traits represent consistent patterns in behavior, thoughts, and emotions, reflecting an individual's tendencies across various situations. For example, extraversion, a well-known trait, manifests in individuals as talkative, energetic, and enthusiastic behaviors. These traits are stable over time, offering a reliable framework for predicting how people might act in different contexts. However, they do not define every moment of an individual's life. In contrast to traits,...

Area of Science:

  • Aquaculture
  • Animal Genetics
  • Quantitative Genetics

Background:

  • Zebrafish (Danio rerio) are important models in research and aquaculture.
  • Breeding programs aim to improve economically important traits like growth.
  • Understanding genetic parameters is crucial for efficient breeding.

Purpose of the Study:

  • Evaluate genetic parameters for a two-generation zebrafish breeding program.
  • Determine the optimal selection criterion for improving growth traits.
  • Identify the best statistical model for genetic evaluation.

Main Methods:

  • Established a base population from six commercial zebrafish stocks.
  • Evaluated two generations (780 and 781 individuals) using BLUPF90.
  • Analyzed fixed effects (age, density, sex, generation) and random effects (additive genetics, full-sib, residual).

Main Results:

  • Total length exhibited higher heritability (0.30) than weight (0.22).
  • A high common full-sib effect was observed, particularly in the first generation.
  • Genetic and phenotypic correlations between weight and length were high (0.87 and 0.75).

Conclusions:

  • Total length is a superior selection criterion for developing larger and heavier zebrafish strains.
  • The best statistical model included polynomial terms for age and density.
  • Breeding programs can effectively enhance zebrafish growth by focusing on total length.
