Question

. Does it make sense to you? In other words, are plants that you thought might be closely related actually closely related?

On your scrap piece of paper that you attached to the PDF file, list some relationships that surprised you. If you can’t find any, list some that you predicted. But seriously, did you really predict kiwis are more closely related to celery and carrots than to strawberries?

Explanation / Answer

Plants sharing more similarity

Celery and Carrot

Potato and Tomato

Cherry and peach

Strawberry and Raspberry

Plants which are not sharing so much of similarity

Apricot and Birch

Soybean and parsley

Kiwi and soybean

Kiwi and straw berry

They are placed based the similarity in the genomes of chloroplast DNA and nuclear ribosomal DNA. It is not required for the function, but the similarity lying in their genome has bought them closer.

In some cases, what plants we thought to be similar are not showing the same extent of similarity. Apple and peach were thought to be similar, but here they share less similarity. Potato and tomato looks totally different, but here they are sharing similarity. Pear and apple looks similar but the extent of similarity is not seen here. Parsley and potato will look entirely different, but here they are sharing great similarity. Kiwi and soya bean are entirely different, but here sharing similarity of 0.61. Kiwi is similar to the strawberry, but here the similarity is more with carrot and celery.
