Heritability estimates is a portion of phenotypic variation contributed by heredity. Traits in pigs such as ovulation rate and number of piglets produced per year are highly heritable traits. 2. The formula for computing crude protein is equal to the amount of nitrogen multiplied by 6.25. This is based on the fact that ALL protein materials contain 16% nitrogen. 3. Essentiality of a nutrient depends on the factors such as species, age, health, metabolism. 4.The deficiency symptoms of Selenium may be associated
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
