detect differences in the DNA sequence

• phenotyping

• genotyping

parent plants are selected based on observable traits

• phenotyping

• genotyping

What is 1 benefit of using genotypic or molecular breeding methods?

• pinpoints certain observable traits such as color & yield

• pinpointing specific differences has more accurate results

• involves more trial & error for desired results
