Cell division is involved in the growth, reproductive development and replacement of old cells in organisms. By using only 6 chromosome, draw and label a new cell showing how these chromosomes would arrange themselves during the metaphase of meiosis I. There is one crossing over that occurs between one homologous pair. In your drawing distinguishes between homologous pairs. Compare the process of independent assortment and crossing over. Decide and justify which process has the greatest influence on genetic diversity.
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.
