Here is the actual data from the 2nd generation of Mendel's experiments. Calculate the ratio of dominant
offspring to recessive offspring for each characteristic, (do this: Dominant trait / recessive trait)
Characteristic
Dominant Trait
Recessive Trait
Ratio (show your work)
Flower color
705 purple
224 white
705 / 224 = 3.15... so 3.15:1
Seed color
6,002 yellow
2,001 green
Seed shape
5,474 round
1,850 wrinkled
Pod color
428 green
152 yellow
Pod shape
882 smooth
299 bumpy
Flower position
651 along stem
207 at tip
Plant height
787 tall
277 short
14. Round off all numbers in the ratios to whole numbers. What ratio do you get?

The ratio between yellow and green seed colour is 3: 1. The higher ratio of yellow colour occur because the yellow colour is dominant as compared to green seed colour.

The ratio between round and wrinkled seed shape is 2.95 : 1.

The ratio between green and yellow pod colour is 2.82 : 1.

The ratio between smooth and bumpy pod shape is 2.95 :1.

The ratio between along stem and at the tip of flower position is 3.14 : 1.

The ratio between tall and short plant height is 2.84 : 1.
