In a population of cats, 12 cm^2 is the additive genetic variance for lenght of tail and 16 cm^2 is the total phenotypic variance. Based on these answer the followinng ques: Find the narrow sense heritability for this length of tail in the population of cats. What would be the covariance of two cats who are related to one another as being first cousins?
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.

Understanding heritability is essential in genetics and biology. Heritability measures the extent to which genetic factors contribute to the variation in a particular trait within a population. It provides insights into how much of the variation in a trait can be attributed to genetic differences among individuals.
