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.
Explain the events that would lead to uniparental diploidy in an organism
A mutation in genetics is an adjustment to the nucleic acid sequence of an organism's, virus's, or extra - chromosomal DNA. DNA or RNA can be found in the viral genomes. When two copies of a chromosome derive from a single parent rather than from the mother and the father, this condition is referred to as uniparental disomy. Uniparental dysomy can result in illnesses including Prader-Willi syndrome (PWS) and Angelman syndrome (AS).
