What makes an organism’s genome the best source of data for creating a cladogram?

The Cladogram is an diagram used to represent the evolutionary relationship between the organisms.

Explanation:

Cladogram is based upon the DNA of different species of animals. It is a qualitative illustration and it doesn’t show the degree of change between the organisms.

Cladistics use the shared derived characteristics of the organisms to establish relationship between them because it is a strong proof of shared ancestry.  

To study all these features the proper data of the organism’s genome is very helpful because provides required data to draw a cladogram more effectively.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
