Question

select the correct answer from each drop - down menu.
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 heterozygous for pea color. because there are only two options for pea color, the plants pea color is a case of
options: polygenic traits, semiconservative replication, simple mendelian genetics

Explanation:

1. For the first dropdown, when two yellow pea plants produce green offspring, the parents must carry the recessive green allele while showing the dominant yellow phenotype, meaning they are heterozygous (already correctly selected).
2. For the second dropdown: Polygenic traits are controlled by multiple genes, which does not apply here. Semiconservative replication describes DNA copying, not inheritance of traits. Pea color is a single-gene trait with two alleles (dominant yellow, recessive green), which fits simple Mendelian genetics.

Answer:

First dropdown: heterozygous
Second dropdown: simple Mendelian genetics
