Please help me with this question

A

Explanation:

I learned this last year, If purple was the dominant and white was the recessive it would be 75% purple and 25% white because purple is more dominant then white.

answer: a. a gene that causes a specific trait.

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
