In a cross between a pea plant that has smooth yellow seeds with a second plant of the same genotype, what proportion of the seeds will grow up to produce smooth green seeds

It depends on which is the dominant and which is recessive for starters let's say yellow is dominant (Y,Y) and green is recessive (g,g). 100% percent of them will be yellow carrying the green recessive trait if it's proposed as this (Y,y) (G,G) it will be 50% yellow and 50% green, (y,y) (G,G) it will be 100% green

The answer is hilum.
