1. Heritability: Heritability refers to the proportion of variation in a trait that can be attributed to genetic factors. It is often expressed as a percentage, with higher heritability indicating that genetic factors play a larger role in determining the trait. Heritability can vary depending on the trait and population being studied.
2. Heroism: Heroism refers to the qualities or actions of individuals who demonstrate exceptional courage, selflessness, and bravery in the face of danger or adversity. Heroes are often admired and celebrated for their noble deeds and willingness to sacrifice for the greater good.
3. Genetic advance: Genetic advance refers to the improvement in a trait or characteristic of an organism that is achieved through selective breeding or genetic manipulation. It is often used in agriculture and animal breeding to enhance desirable traits such as yield, disease resistance, or growth rate.
4. Variance types: Variance refers to the variability or spread of values within a set of data. There are several types of variance, including genetic variance (variation due to genetic factors), environmental variance (variation due to environmental factors), and genotype-by-environment interaction variance (variation due to the interaction between genetic and environmental factors). Understanding the different types of variance can help researchers better understand the factors influencing a particular trait or characteristic.

Heritability
- The proportion of phenotypic variation in a population that is attributable to genetic variation.
- Expressed as a percentage.
- Important for understanding the potential for genetic improvement and predicting the response to selection.
Heroism
- Exceptional bravery or self-sacrifice in the face of danger.
- Often attributed to personality traits, upbringing, or situational factors.
- Can have a genetic basis, but the heritability of heroism is complex and poorly understood.
Genetic Advance
- The improvement in the genetic value of a population over time.
- Achieved through selective breeding or other genetic manipulations.
- Depends on the heritability of the trait under selection, the selection intensity, and the generation interval.
Variance Types
- Phenotypic variance: The total variation in a trait within a population.
- Genotypic variance: The variation in a trait due to genetic differences between individuals.
- Environmental variance: The variation in a trait due to non-genetic factors, such as environment, nutrition, or disease.
- Additive genetic variance: The portion of genotypic variance that is due to the sum of the effects of individual alleles.
- Dominance variance: The portion of genotypic variance that is due to the interaction between alleles at the same locus.
- Epistatic variance: The portion of genotypic variance that is due to the interaction between alleles at different loci.
- The proportion of phenotypic variation in a population that is attributable to genetic variation.
- Expressed as a percentage.
- Important for understanding the potential for genetic improvement and predicting the response to selection.
