What do these characteristics all have in common?

(Characteristics in the picture)

They are all dominant.
They can all be easily observed.
They are all recessive.
They can all be applied to other plants.

They can all be easily observed.

Explanation:

One distinguishing feature that Gregor Mendel watched out for in Garden peas was that all characters were easily observed.

Thus, he could easily differentiate between wrinkle and smooth peas, tall and short pea plants, purple-color seed and yellow-colored seeds etc, all because they the traits could be easily observed

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

the match lol
