Is my dichotomous key correct?

Postby cactus » Tue Oct 03, 2017 4:47 am

Hi all
For an assignment I am required to create a dichotomous key for six fruits. They are: Apple, Pear, Orange, Banana and Strawberry. Here is the key I created:

1a, Spherical shape…………………….. 2
1b, Aspheric shape ……………………… 3

2a, Thin skin………………………………….. Apple
2b, Thick skin………………………………….. Orange

3a, Seed bearing…………………………… 4
3b, Seedless………………………………….. 5

4a, External seeds………………………….. Straw berry
4b, Internal seeds……………………………… Pear

5a, Elongated shape………………………… Banana
5b, Scaly skin …………………………………… Pineapple


I am not sure if this is correct or not. I am not sure because I am quite new to this.
Help would be much appreciated!
Thanks,
Sam
