Genes are segments of dna that determine the phenotype of an individual. pea colors can be yellow or green. when two plants that produce yellow peas were crossed, the offspring produced green peas. this is because the parents were __blank__ for pea color
1: heterozygous
2: homozygous dominant
3: homozygous recessive
because there were only two options of pea color, the plants' pea color is a case of
1: polygeneric traits
2: semiconservative replication
3: simple mendelian genetics
