Answer:
Law of Independent assortment
Explanation:
Gregor Mendel, who was regarded the father of Genetics, discovered principles that governs inheritance in his experiments. He discovered that the alleles of a gene will separate into gametes when he performed a crossed involving a single gene or character like height, pea color etc. He proposed his law of segregation based on this.
However, he considered two characters or genes in his cross, which he called a DIHYBRID cross. He discovered that the alleles of each different gene separates into gametes independently of one another i.e. without one gene influencing the other in each gamete. He called this principle his LAW OF INDEPENDENT ASSORTMENT.
He obtained a 9:3:3:1 phenotypic ratio for the F2 dihybrid offsprings which is only possible if each gamete equally likely contains two alleles of the two different genes in different combinations.
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
