traits studied by mendel
plant height\ttall\tshort
flower color\tpurple\twhite
flower position\tend of stem\tmiddle of stem
pod color\tgreen\tyellow
pod shape\tinflated\tconstricted
seed color\tyellow\tgreen
seed shape\tsmooth\twrinkled
what do these characteristics all have in common?
○ they are all dominant.
○ they can all be easily observed.
○ they are all recessive

Explanation:

1. Analyze the first option: Some traits like short (plant height), white (flower color) are recessive, so not all are dominant. Eliminate this.
2. Analyze the second option: Traits like plant height (tall/short), flower color (purple/white), seed shape (smooth/wrinkled) etc., are all visible and can be easily observed. This fits.
3. Analyze the third option: Traits like tall, purple, inflated etc., are dominant, so not all are recessive. Eliminate this.

Answer:

B. They can all be easily observed.
