Wollemia nobilis, family Araucariaceae, phylum Coniferophyta, was discovered recently in a National Park in New South Wales, Australia. This stand of trees is remote and difficult to access. These trees can grow to 40 meters tall. Sadly, this stand of trees has been infected with Phytophthora cinnamomi. An extensive breeding program was undertaken and now this beautiful and ancient tree is readily available for purchase. The common name for this tree is the Wollemi Pine. Answer the following questions in sentence format, that are related to the above case study. e. How did Phythophthora cinnamon enter this remote location to infect these trees?
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.
