In experiment of genetic drift, suppose you have a population of 300 butterflies. if the population experiences a net growth of 12% in the following year, how many butterflies do you have? Now supposed you have 300 eggs, but only 70% of those eggs become caterpillars, and only 80% of the caterpillars become adult butterflies. How many butterflies do you have? (For simplicity, assume that all butterflies survive to the next year in this example.)
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.
