1. 2. 3. re the 4 1) OVERPRODUCTION - What leads to over overproduction? Observations Overproduction of offspring 2) Variation needs to be: Individual variation : When a genetic trait becomes more abundant in a population because it helps you to get : About Genotype - Conclusion Natural selection: unequal reproductive succe
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.
There are a few important points :
- Evolution helps us to understand the history of life.
- Character changes by the environment during the life of an individual.
