2. Can the classification system change? If so, provide an example of a way it has changed in the past. (2 points)
Elis [28]

Yes, classification system is still evolving together with our knowledge.

But, before changing the name (e.g. of a species) it is important to collect and gather a wealth of information in order to support that change. Classification system is still evolving. The reasons for the changes are DNA analyzes. It is the new way for discovering relation between organisms and put them in the right context (classification used to be based on morphological characteristics).

Change in classification can be shown in an example of fungi. In the 90s fungi classification included only phyla Chytridiomycota and Zygomycota. Now theyhave been classified mainly on the basis of characteristics of their sexual reproductive structures. So, there are 7 phyla now: Microsporidia, Chytridiomycota, Blastocladiomycota, Neocallimastigomycota, Glomeromycota, Ascomycota, and Basidiomycota

The genetic fault that usually causes colour vision deficiency is passed on in what's known as an X-linked inheritance pattern.

This means:

1) it mainly affects boys, but can affect girls in some cases

2) girls are usually carriers of the genetic fault – this means they can pass it on to their children, but do not have a colour vision deficiency themselves

3) it's usually passed on by a mother to her son – the mother will often be unaffected as she'll normally just be a carrier of the genetic fault

4) fathers with a colour vision deficiency will not have children with the problem unless their partner is a carrier of the genetic fault

5) it can often skip a generation – for example, it may affect a grandfather and their grandson

6) girls are only affected if their father has a colour vision deficiency and their mother is a carrier of the genetic fault
